Compare with the Pencil Sketch if you like :D
I stated before that, this is one of the important stages, of my process at least. If you compare with the original you're gonna see some mayor changes, and for the best.
I usually fix many issues that were a bit off with the previous sketch. Since I have the references at hand, I can easily reshape the drawing until I'm happy with it. Most the times the first sketch just helps me to get the idea of the picture I want as a whole.
And I'm still keeping a little detail from the picture a secret :9 I think it's better that way.
