As far as I can see, it's looking pretty good!! I can see that your art has improved quite a lot. I like the colors in the picture; very vibrant and lively!! The only little thing that I see that could be changed is the size of the character's head. Maybe just make the head a bit smaller. Otherwise, I don't see too many other faults. :-] I like how you drew the sky, very fluffy clouds! It also helps to experiment with different backgrounds, like a night-time setting and such!
You're doing an outstanding job, my friend! Keep up the good work, and remember to keep practicing!
