Nice! I like the composition of the first one. The colors give a warm sunset feeling to it, which I like, so that's a plus.

Second one maybe isn't as good as the first one, but it's much funnier to look at. :P I want to have a place where I can do that! The colors seem a little oversaturated in the sky, which looks a bit unnatural.. And btw, what is that in the lower left corner? Something flew by or something, leaving like a light curve there. Weird. :P
