Size of it is pretty massive. However, it's a simple design. Personally, I think the shade of gray that you used for the star is a little too dark. If you were to lighten it up a bit, the character's head would pop out a bit more.Haha yeah buddy it looks pretty simple, its just that I've drawn the whole thing with a bruch except for the Star, I used a star and added effects to it and made it like this, shadowed and stuff, thats all about it, it was only from scratch.
But it's nice for a super simple design.
