I like what you are going for but the contrast between the tie and jacket may be too much. Perhaps a richer brown, a la Slewfoot's fresco project, would be much better.
It's a very rich (varied) brown, bah - I hate the iphone.
Suggestion from someone who still knows very little about photography but has through trial and error learned how to take better pics with an iphone - Instead of doing the mirror thing, stand facing an open window. Turn the phone around so that the screen is facing towards the window (I know there's a camera on both sides, but the camera on the screen side is not as good). If you're lucky you'll be able to see enough reflection in the window of the screen that you can aim at the right stuff. Take 6 or 7, moving the phone around a little bit. Pick one and post.

and this brings up another point, the quality of the pics many times is as much a determinant of the type of criticism as the outfit is. A very nicely lighted pic goes a long way to making an outfit look great and vice versa.
