I like the lighting in #1. The rainbow could stand some punching out.
#2 doesn't seem to draw me into it. Possibly because the photo is bisected vertically. I think the tufts of seeds on grass blowing in the wind would pull me toward the back of thetreeline if the shot were taken at a different angle. The horizon is off and the powerline fading into nothing is very distracting. I like the lighting/color in this one also.
There is some excellent potential- you are seeing the shots but need to work the elements to show others what I think you are feeling. I'm looking forward to seeing some more of your work.
