I just wanted to point out some minor things. They are easy to fix and nothing breaking, but you might want to change them for your official download.
1. The Metal-Statue in all versions is moved too far to the right by 2 pixels, covering up part of the Flora-Statue.
2. The Metal-Statue in both Elemental Dungeon sizes is one pixel higher than it is supposed to for the 192/128 height.
3. The most right line of pixels for the base's shadow is a bit darker between statues if compared to the most right one of the sheet.
Have a nice day and keep up the great work!
