The composition is very strong overall, though I'm not sure where the title will go without things feeling crowded.
The character at the back is so much more detailed than everyone else in style that it's drawing all my attention. I get the feeling you're going for an "othering" effect where the more detailed character looks creepy, but the detail level and particularly the hatched rendering and different line style make it feel like it doesn't belong in the same illo as the other characters. Would a version of the character with a lower detail level for more stylistic consistency maybe work a bit better? That or remove the top figure and put the title in a clean space at the top?
