It's great! If you look back at my first Conan drawings, they look... *shudders*
Anyway, I think the only adjustments you have to make are the ears, eyes, and jawline. The ears stick out a bit too much, and Gosho usually draws them with more flesh. The eyes are in a different style, too: he usually doesn't draw the line all the way around and he has a rectangular 'sparkle' in addition to the standard anime one. The jawline is just a bit too sharp.
+1 for you~
