These images make me smile.
First image: Fantastic Sky. Great textures on rocks. Not enough separation between subject (rock) and foreground. You might try some local contrast enhancement.
Second image: Love the contrast between stone and flower. Great textures. This is a nice pattern piece. Again, some local contrast enhancement on the rocks may help a bit to make them jump off the page a bit more.
