A CRITIQUE YOU SAY? WELL ALRIGHT!
I like this drawing. the end
No, really, it is quite good. I am terrible at drawing humans or anything resembling a human. Faces and human bodies just confuse me to the moon and back. But this is good! The only things I would like to point out are:
1) The space between the nose and lips is a bit large. Just a tiny bit.
2) The eyes are a little bit big, proportionally speaking, and in regard to Toby's eye size. He has slightly small, kind of squinty eyes. The eyes in this drawing are good but the size makes him look more cartoonish (which is maybe what you were going for?) but it also makes him look really young in this. I know Toby does look young for his age but not quite this much.
3) And finally, a little more detail on the ears would make the whole drawing more realistic. Ears are a pain in the ass, all those curves and lines and I always get them wrong, and everyone has different ears. But if you added some detail it would bring your drawing to life more.
I HOPE THIS HELPS YOU
PEACE OUT. BOOP
