But, if you're going to do a cartoon, some AA and darklights are in order here.

 

Also, just a forewarning, tracing a picture, especially someone else's art (Homestar here was drawn by someone else), is looked down upon. In fact, because you've traced someone else's artwork, this may be a rip. It doesn't sound like that was your intent but... usually the only tracing "allowed" - for lack of a better term - is tracing of reference photos (preferably your own), photos of real things in life, not of cartoons.

 

At any rate, why do Homestar? why not make your own character and be a little more creative?
