Need Hints and tips with Vex Characters

[~R~]

I decided to use the Vex template for my game, as it looks pretty nice to make positions and the style matches to realistic and modern games.
The first one i tried making a position, and as it looked good in my opinin (Except by the shadow i made below him):

The style was matching what i want, so i made the same character walking:

Is there something i could improve here?

He switches to a different jacket, a striped one at that, when walking to the sides?
It really looks less like shading and more like an attempt at making a jacket with like, horizontal pin stripes.

Also just because I nitpick, the jacket nearly covers the shirt in front view, but so much is exposed in side view - as if he puffs out his chest just for those directions for no reason.
