As for the second, I really do like the colors. The pentool work is a bit random and sort of detracts from the possibility of a natural flow. The blur is a little strong for how hard you'd erased parts of it out so it seems sort of splotchy. I'd remove the blurring layers entirely and if you're confident add a very, very soft blur to the background plain to bring your focal forward.
