Hello everyone, I'm new to the world of micro stock and need some feedback regarding image quality more than anything. I'm wondering if these photos are acceptable with noise, exposure etc.?

Feel free to leave comments about composition, focus, WB, or anything else appropriate. I know there are copyright issues in a few, but these aren't planned submissions. I'm more concerned with quality of sharpness and noise levels. They seem good to me at 100% What do you think? Thanks in advance if you've taken the time to help me!
