Thanks for the responses. I am using smooth preview currently as I am not too fussed about keeping the model super low poly. In regards to giving the character a colour boost I have added a 'nice' bright background to give it a it more interest, though the Hawaiian shirt does sound pretty cool, I think I might leave it for this project depending on how much time I have.

I have now hand painted a new diffuse texture, keeping in mind the grunge element NextDesign mentioned especially on the jeans, but could realy do with a few pointers on the skin texture as this is where I am having troubles getting it to look right. I still need to create the bump and specular for this model also to really brink it to life.

silkroadgame can you be more specific about how I should ho about updating my UVs. They have changed slightly from the screenshot above, but I still feel that I have a few layout issues.
