Silly to ask? Definitely not. Developing a drawing style that's all your own is no easy task.
Stylized cartooning is a tricky thing indeed. I spent years developing a style for myself that I was comfortable with and yet still felt "original". You want to develop your own aesthetically distinctive style, but you're stuck with copying as the only means of cultivating said style.
What you want to do is select several different styles and combine the elements that you find most visually appealing. Bodies, facial features, clothes, whatever. Find specific examples of what looks good to you and then put it all together in drawings. Then, slowly, you can introduce your own personal flare. My signature physical trait is eyes. They are always much more detailed than the rest of the drawing and, even though other attributes change from character to character, the shapes of my eyes do not, because they visually define my artwork. For you, other physical traits may be visually defining, like hair, clothes, or body shape.
