/ic/ - Artwork/Critique

Hello /ic/,

first time poster since '07 or something. Anyways i thought this thread might suit my question also.

I've been going through this world in my mind, related to the pic. I don't know how much people here go out, but you might have seen those "islands" on swamps and fields. Those are in my eyes somehow really mystical and hard to reach, so i've been creating this story around it. What kind of animal-like creatures would you see walking around with these islands on them? I'm trying to find some rough, yet friendly form for it - not any hippo type or such, im trying to find a solution that also suits scandinavian scenery.

I've been lately working on birds too, so I see a connection with these animals and setups. So, any critique/feedback?
