It's hard to debug from this picture because there are honestly a lot of potential failure points. Not to mention, it might not even be the soldering at all. You could potentially have overheated one of the parts (it takes a lot of heat to lift a pad), or you could have shorted something if the soldering is incorrect. Since these don't look like expensive components, I think it might be easier to start over (if possible), work very slowly, and try to keep the soldering very clean.
