Picture is over-exposed. Lighting is too strong creating a very flat look. You need to work on controlling the lighting more so that you've got some shadows to add depth and contrast to the picture. Also, the eyes do not look like they are in focus. Best is to use to single point focus, focus on the eyes, then re-compose. If you want some of your background to be part of the picture, meter your shutter speed off the background first and shoot at that shutter speed. If your background is very bright, this will under-expose your subject. To correct the under-exposure on your subject, use either a reflector or off-camera fill flash either camera left or camera right depending on the look you're going for. If you want to get serious about this, you have to get serious with off-camera flash, reflectors, modeling poses etc. Good luck!
