I think you need to be more specific.

need some good tips or tutorials in-depth about light and how to use it properly , and what its the best practice to create assets with blender , precisely UV mapping .

If your answer its : search on web . I already did that .

Another way to help me its download the project and tell me how to improve the light

I will eventually looking for artist to create some assets like this one here

and pay for it .

Sorry about lack of information i provide early .
