The mermaid(?) looks good, but the bearded person seems to be in sideview rather than 3/4 view. We should see more of the top of their head, and their trousers should probably have more of a curve around the body.

I also made his beard stretch more around his head to serve as another perspective marker, removed the highlights from the cheeks because I don't think they read well, and made the highlights a little darker because their brightness was overpowering the other skin colours, making the skin shadows not read well.
