Rock Wall with textures image - dinky

This is the low-polygon model for a rock wall that I sculpted in ZBrush, and it's being rendered with Advanced OpenGL inside of a modo viewport. The diffuse texture was hand-painted in modo as a test, and the normal map was generated using xNormal that you can get from Xnormal.net

There are a couple of problems with the normal map, nothing major. But the seam that is visible there on the right side is because of the texture painting in modo. Also, there are a couple of hard edges, and this is because of the modo viewport.

I actually am pretty satisfied with how the maps are generating, I just have to make a better diffuse map. ^_^
