Yeah, thanks Jax. I'm with you, it also feels 'wrong' to me. I don't think, it is the color (anyway, it could become a bit more white, you're right). I think it is the kind the shards are arranged. I drew it before I had better reference images than those two on top. The files in Redrobes link are like 50 mb large - I don't have DSL actually. No chance for me to get those images right now.

I also asked myself, if ice shelf would exist in a region between two lands, while in the northern sea no more ice shelf is. I did not find an answer yet. Located north of the large island still is an other island. The northpole, so to say. Is it possible, that ice shelf is not only around the arctic poles? Okay, it is a fantasy map ... but I do not feel comfortable with a world that does not obey our physical laws.
