No probs man,

just work on the lighting a bit before going onto the textures, give him a nice "rounded" lighting ie theres no completely dark shadows and nothing really white (as long as your using the default lambert). that way you can get an idea for the look of the scene.

Apply your textures form there then adjust the lights to match.

Its not a be all and end all mind you, depending on your project.

Hope it makes sense
