Sorry but I don't have time for something like that.. I guess general illustration and painting rules apply to matte painting as well. Realistic illumination, good perspective and nice composition.. Start from sketch and big strokes with no detail, keep refining and detailing later.. etc.

I don't know your level, but for general painting tips I love this old tutorial http://www.androidarts.com/art_tut.htm

For any specifics, don't hesitate to ask..
