Agreed #1 is way too soft. The thing that bothers me and doesnt..is the left arm. I tend to crop like that alot..a "missing" body part or limb can sometimes add to a photo but there should be some hint that it is at least there. I also think she looks reeeeally nervous or like you "caught her" by surprise. I generally like the idea but might try it turning her left shoulder a little towards the lens a little bit. She also looks as though she looks uncomfortable sitting the way she is sitting.
# 2 Two things jump out at me..one could be subjective as my personal taste. I dont care for the position of the model. She is smack dab in the middle of the picture. The second thing that jumps out at me...even though it was actually the first...lol. Is the "big object" at camera right and almost center. Remember...the human eye goes right to what is the brightest..or the most noticable item in the picture. I would have placed her somewhere where the mirror sections did not "cut" into her.
Having said that...I have done all of those things..You dont have to be sick to get better as I say....I am sure even the pros might agree with that statement...the answer is KEEP SHOOTING!!!...LOL. Thats what I do anyways,
