I decided to write a critique because I reaaaally love your stuff and I want to try for once to say something more on a pic of your's.

This is so well drawn You are so good at drawing Sonic characters. The way you draw every part of the character is just.. excellent~ the eyes, the muzzle, the sizes of the hands, body etc... official work You make me jealous really.. I can't find something wrong on this pic xD
I really like the way you chose this kind of pose because although it's not simple (like just standing ones) you can see every detail of the character. And with this "showing off"(xD) pose it just makes the whole picture clear and cool

I don't think I can find any mistakes here.. even the shading is great. You can understand where the light is coming from. Btw I love those shoes xD Very cool character... Awesome job please keep it up!
