Check out this screenshot (Heroes 3 + Photoshop).

The idea is original and looks amazing! I was impressed :) A few comments (IMHO): 1. Fewer repetitions, there are clearly too many of the same devils. But the skeletons, as a crowd of weak monsters that overwhelm with numbers, look great. 2. It would be good to unite the whole picture with a common theme, so that each monster duel doesn't seem detached from the others. 3. I liked the combination of monsters from different versions. Where else can you see that if not in creations like this?! Overall, the author did a great job. It would be interesting to see more works in this style. Even more imagination! Even more originality!
