Have you watched the movie Skyfall? There's a scene in the movie that you'd be able to paint beautifully! It's the scene where the main character is driving past the gates to his old house...one of the side columns is busted, but the other one is still standing with a large deer on top. And in the background there's his old house.
I used some photos too look the colours and shape from. first you get the colours as close as possible without using a colour picker and then use rough brushes to make the shapes...its hard to explain xD I may make some speedpaint videos...
Yes yes, it's pretty easy for me to use colors right. But what I mean is using the right brush and settings, every line I draw looks weird with every brush. And I don't fucking know yet how to make the right modulations xD
Ah well, means that I have to sit more behind photoshop ^^
