1) System set 1 is not the same style as system set 2. This isn't a major deal (more of a pet peeve) but they aren't even the same colour.
2) The black at the bottom does not look good. Either change the backdrop (which I personally suggest because the quality is poor) or make it work with a bit of editing.
3) The boxes displaying HP, MP and Time cut into the facesets. Cut the facesets and position them. They would also look better with a border (the same that surrounds the system set 2).
4) Your main character battleset is female, while the faceset is male.
