Here's a few comp ideas for Jason's commission. I like the basic pose on the first page, though I may want to flip the characters so the red dragon's scars are visible. (It looks like they're all on the left side of the body in the refs.) I really like the layout in the mini sketch at the bottom of the page. It's more dynamic looking.
This page, meanwhile, I don't like as much. Everyone seems a little too stiff and crowded. It happens sometimes.
edit: And here's the re-work of Alex's comp sketch. I did this one digitally in case I need to make a few more changes. Hopefully it's coming along okay.
