WOAH. I love the colours: you seem to have a knack for choosing vibrant, natural palettes. Your brush strokes as well seem individually random but cohesive and designed on the whole. I especially love the top two, and that moon/planet in the distance.
The beast is awakened. Man that first one is all sorts of chunky goodness. Very strong shapes going on, I am digging it a lot. #2 has some insane colors going. It has this very free and peacefulness about it with some nice attractive vibrant colors. And #3 you did a great job emphasizing the difference in the atmosphere...shit that made me look back to #1 and I just saw the planet! Damn...these are sick nasty my friend.
