Your sprites are decent but they are not the absolute best to be quite honest. Your Scratches are much better! I believe that your scratches are much much better than your actual fusions/splices. I can see some in a Fakemon game. If Gamefreak was to select one of the evolution chains, it would be your first splice.
The rock giant is absolutely amazing! It has numerous details and the coloring is just right. I believe there could be more details in the evolution but for a scratch, it is amazing!
Now there is a significant change between your first Fakemon and your Second Fakemon groups. Your first are ok but your improvement is outstanding! You are a great artist and I hope that you keep up the good work!
