I think the rules state that you cannot make a showcase thread solely out of fusions. Even though I think this thread would be locked or moved (unless the rules had changed), here are my points:
First, the black outline ruins everything. What I mean is, the black outline makes the viewer reluctant to view the sprites just because of some kind of feeling. Secondly, I would like to point out that the whole image is in JPG format, obviously because you used tinypic, which is not so picky about image formats. JPG format distorts the pixels, so NO possible criticism can be given. Lastly, I think your concepts are really good, though I cannot be certain due to JPG quality. I like the Chandeluxxe in special. Reinuculus + Castform is good too. Please re-upload the whole thing and hope it is not JPG format.
