Gun on ravine

[lordmathayus]

Hi everybody...this is my new wip! The subject is a gun made in Blender. The plane shown as background will contain a texture about a see with a orange/red sky full of clouds. I'm setting up the light but i've some problems with it...i don't find the right way to put them into the scene. Do you have any advice?

This is Side View:


And this is Top View:


Thank you so much to all...
