First...Dont compare yourself to others here. You are you and are at your level of photography. Do your thing and learn and you will get better.
Now for the image. The blur, if you added it, is too much. To me it looks like an out of focus shot. You need to get your model away from the background as well. The pose looks like it is ok, but to be honest the blur takes so much away from the image that I find it difficult to look at. Hurts my eyes. Anyway, keep shooting and learn from the advise people give.
