It's good to see perspective studies, I think it's so important to hammer into our skulls perspective drawing so we can visualize it on the fly. Your speed paintings are also starting to look quite good. As for the last painting you did, I recommend defining the object in the sky more, I can't tell if it's the hollowed out inside of a cavern, or clouds. Maybe look at volcanic rock shapes like this http://us.123rf.com/400wm/400/400/namein...-sprou.jpg which has the smooth surface you're looking for if you're going for that look. If they're clouds I recommend blending more and using different brush shapes and erasing/smearing them around. And as always, references are our friends :)
