Your style is different than others that I've seen. Your style is the type of cute like and I've never seen a drawing of yours that had the whole anatomy of your character. I say your characters look the same and this one, he's supposed to be more manlier looking than this and he's supposed to look different but it's your style.
The coloring is nice, the shading looks great. The outline of his head is darkened to show how sharp it is. It's nice to see the black color to show his shadow but it's not working as much.
Nice character drawing overall and keep it up!~
