For what they are worth...
#2 is a very nice image... beautiful gradients, etc. in the colors...
#1: the main subject (the leaf in the center) is unfortunately overexposed - it would've been a great shot, but the highlights are blown out.
This is where a CPL would do wonders for you - it would remove the blown out reflections. Did you shoot in RAW? If so, you might be able to recover that somewhat. Let me know if you're willing to let me try it if you cannot - may not be right away that I can do it though since I am fairly busy today.
Again, #2 is wonderful - very, very compelling colors!!!! A sincere handshake for doing so well.

Marc
