I've decided not to link my book directly on the forums, but I can drop you the details in PM. I published my book under a pen name.
I haven't made a lot from it, but the good thing about self-publishing is your books can stay up for sale indefinitely (whereas books through a publisher typically have a certain lifespan depending on sales). It means that if at some point in the future one of your other books takes off, one you published before might as well, and the royalties might trickle in for the rest of your life. There are so many books out there though that without marketing efforts or some other reason the book would be found, it might not be. I have a web site for mine, but to some extent it's a work in progress. I should add some more content. I'm also planning to put my book on Smashwords now that I'm no longer locked in to Kindle Select.
I have some of my artwork up on here
. I don't think any of the art on E is in my first book, because I only started drawing most of those images afterward (since May or June this year). The drawings I used in it were more surreal type art for the most part. The ones I have on Elliquiy are more ones I'm creating with a view to including the best/most relevant of them in the next book. These ones also use more Photoshop brushes I bought the licenses for, so I can include them in my own work without giving credit to the brush creator if I want to. I do it anyway because it's respectful to do it and it might help drum up some more business for her at the same time. It doesn't cost me anything to mention her name/web site.
Regarding studying, a lot depends on the job you're aiming for. A lot of companies won't hire you for a qualified role straight out of college. You need experience, either with an internship or somehow working in the field. I know from when I was in college that some people who were successful in finding jobs straight after were working/interns in companies while they were studying. By the time they graduated, they had experience. Others had unrelated experience but they had work experience and it helped.
Personally I don't like internships. I've looked into them and I'd have been working for nothing or next to nothing, and there are costs like transport and lunches that they probably wouldn't cover. Over here, a lot of jobs that were 'entry level' have now become internships. Anything can be an internship. I saw an internship for selling bread in a bakery. People are taking advantage of loopholes to hire employees cheaply. Over here there's an internship scheme that will top up benefits by 50 euro if you're on them and take an internship, or you'll earn 50 euro a week if you're not. Basically, all the company is doing is paying 50 euro a week to hire someone on full time, and an internship lasts between 9 and 12 months. They say it helps get people into jobs (some internships may lead to jobs afterwards) and there are cases where it does, but I also know people who have 10 or 20 years work experience, have studied at university level and they're earning next to nothing as interns. They should have better options than that. One guy who was on my team in my last job has been doing an IT support internship for the last 6 months or more, even though that was part of his paid job description in his last job. Maybe he will do well out of it in the end and get a job there, but there's no guarantee. People are taking advantage, and while for him it might benefit him because it means he has some money coming in, companies should be paying their employees properly if they expect them to turn up for work every day and do what's required of a job. It costs money to live. I'd say if you don't have any or much experience, consider charity work, temp work or something like that. Then you have something to put down on paper and it shows you can work with members of the public.
I've totally gone off track with my bit of a mini rant/ramble, but anyway, an arts degree is more suited to jobs or interests in the area you've studied. You need to be able to apply it in a job interview setting and explain what you gained from it or how its unique skills apply to the role you're looking for. Even if it comes down to being a more well-rounded, knowledgeable person, there is always something. If you call your degree useless or believe that it is, other people will pick up on that and adopt your view. If you put a hell of a lot of work into it and learned from it, and grew from studying it, then it does have value. With arts degrees, I've found these are well-accepted for office-based roles.
