Mr. Zurkon

Hello!
I decided to create some Ratchet and Clank fan art for practice.

If you don’t know Mr. Zurkon, here’s an article about him: http://ratchet.wikia.com/wiki/Mr._Zurkon

I hope you can give me some tips on how to create the textures, because the modelling is pretty simple, but I want to draw the textures myself.

I think I’ve finished the modelling now!



I’m still not sure, what style I want to go for with texturing and whether I can achieve a realistic looking robot doing texture painting.
And I have a question: Is it possible to mirror texture painting? I know that the mirror modifier has a mirror UVs option, but it makes the textures overlap.
