Blurring the background can make or break a signature. In this case, I feel the background is blurred a little too much. You want to create a nice sense of depth, so be careful when blurring objects, backgrounds, etc.. I also feel the text draws away the attention of the focal. Some people aim for this..however usually the image is to be the focal point except in cases of some ads and whatnot. I do however like your placement of the focal point and the text is in the right area, just needs to be downsized in my opinion.
