We may seem scary, but we're just GMs. If you're unsure, the best thing you can do is fill out a tentative sheet and PM it to us. We'll look at everything and let you know if anything needs fixing. <3
If you're REALLY unsure, fill out the stuff like history and bio information (the kind of stuff that we can only help so much with) and we'll offer up some suggestions for attributes, skills, gear, etc. and you can decide whether they seem to fit your character.
But yes. Either way, send what you have to us, bury us in questions, and we will answer them as clearly as we can so that things are a bit easier on you. ^^
