UV mapping & Texturing

UV mapping & texturing was difficult for me since i had a hard time getting used to it, i got the mapping and texturing in the end but was and still am really tentative when using it. One thing i didn't do was bump mapping since i found it difficult to get to appear how i wanted them to. I know that white is top and black is at the bottom on the bump map but i felt that i should try this more during my own time when i have a long period of not doing work to get better at it.
