Not bad at all, you even got the shading for his feet to look good. I can NEVER manage that! The only thing off is that the helmet is a little lopsided. I take it you kept the paper straight when you drew it? I have that problem as well. I can't draw anything that is both symetrical and tilted unless I turn the paper a little.

All in all though, I like it. Nothing says "You will find me both adorable and epic, or else" quite like winking Kirby. If you make a second attempt, as most artists do now and again, I will most certainly check it out as well.
