Smaller eyes eh, uh oh you're headed for realism ;D

Or perhaps not, it's just a trend I've noticed with a few of my friend who start off drawing anime and slowly develop their own style (in my case I never had particularly large eyes but still have limbs that go on for the better part of forever).

Most very definitely improving, you will do that out of sheer repetition anyway but it's happening so much faster because you're consciously working at it :D
