I really like the last one, but the first two are so similar. They don't seem...different enough. Lol. I loved the last one though! It was awesome! Keep up the good work!
1. I love the colour and atmosphere of this photo. The focus on the guitar is good and the lighting is beautiful. I wouldn't suggest changing anything.
2. The contrast of the guitar against the black and white background is effective but I think you should have cut around the person more carefully -- I'm assuming that you've cut him out and pasted him on top of this second photo?-- because he's missing quite a bit of his head and there's some white around his body. It's a good photo though and there's a nice use of space.
3. This one really doesn't catch my attention. It isn't focused enough and there's nothing interesting about the background.
If you have built castles in the air, your work need not be lost; that is where they should be. Now put the foundations under them. — Henry David Thoreau, "Walden"
