Wow, this is really impressive; that’s a huge amount of characters to get into one piece, especially as they are being rather detailed in their design and “costumes”. Seeing some classic pencil work is quite a treat too!
I think Pyrex is my favorite here; I love the choice of colors you picked forr his outfit, it compliments the character very well. Great work on getting that metal to look all shiny too. But Road Kill is darn cool as well, I simply love the boots and coat there.
Willow is certainly being the cutest though, with that hood and being notably smaller then the others ^^
