yep, morghen, the main front panels and leg panels are UV mapped with textures i painted in photoshop, most other things are just textured in various ways! I'm not an experienced texturer so im sure it could look a lot better than it does!
I'm still unsure of the colours, i had a bit of a play this arfternoon and the typicalrobot colour schemes just look really bland and i start to miss the bright blue!!!
Here is a pic of the actual Ultramarine Dreanought from Games-Workshop:
