It's pretty good, actually! Your style of drawing people works well - only thing I'd suggest is making your lines less wobbly in terms of thickness. Can you tell me a bit about how you draw lines so that I can advise you on how to remedy this? Otherwise, nice work!
Edit: No, you're not dumb! It's just something a lot of people don't pay attention to when they're starting out drawing, that's all! Okay, so the next couple times you draw something with this program, pay attention to what your hand is doing when you draw the lines. Is it wobbling a bit? Do you end up drawing multiple lines and then erasing the ones that don't work? Etc. :)
