My two latest renders, just thought i'd try to get some feedback, as i thougt they turned out well for the most part.
I think the forested hills could use more sunlight streaming through the clouds. I would try to have the light focus on the center hill.
The second, desert render, needs some foreground work. Some stones or sparse clumps of vegetation. The lighting seems better on this one.
I would give image 1 some more head room. You should break the line of frame with your subject or stay further away. Coming so close to the top of the frame like that creates a very bad visual tension. I think with this change and a little lighting work it will be a strong image.
