Realistic BoxTrot

Hello, this is my first try at making a "realistic" skin.

I know it doesn't really fit TF2's cartoony feel, but some people probably want to make TF2 look more realistic.

I tried adding a normal map but it looked terrible...

Anyways, all I did was double the resolution, put some pieces of a cardboard layout onto it and put the other details onto it.

All feedback is appreciated.
