Very nice. :3
I like the first one. I suspect it's CG but the splashes with the water looks like real media to me.
Also very creative creature use with the seahorse-men. Most people don't choose that particular type of seahorse so it's nice to see it.
As for a few of mine.
Sadly these have a few errors I might go back through and correct. I just need to find a weekend to play around with them. ^^;;
