These are so adorable! And I like how you used the old-school bear model, too. They used to look so much more... fluffy back then. Kudos also on both the color scheme and tummy symbol making them instantly recognizable. I just have one tiny little nitpick, though. Jasno's red cross is a bit misleading. I think the Maltese cross would suit him a bit better.
I think maybe "misleading" wasn't the right word as much as "not the most obvious." You're right, it is a standard medical/emergency symbol, but I think Jsano is more well known as a firefighter because of the skin he uses and the station he built.
