More defined bump mapping

I have tweaked the textures, mainly the bump to bring the veins out more and dumb down the lines. I like the lines but I don't think they should be too overpowering as they aren't a main feature of the monster.. whereas the veins are.

Here is what I've got..

So far, I think I am finished with this. It is a low poly model.. at 1927 polygons (faces). the texture maps are at 1024 x 1024 pixels, which is fine for the cut sequences of for an inventory screen but for ingame characters the textures will be altered to 512 and 256 pixel variations for different LOD for different distances. (zoomed in will have higher texture maps at 512 and zoomed out will have 256).
