what aspect are you aiming at? That there seem to be quite sharp corners in the glaciers? That is fine and does not look that extreme when you look at it ingame. At both glaciers a bit of snow is missing around the border, but the materials are anyway still wip, so this will be fixed.
Well, they don't are the best glaciers, but in nature you just can't find perfection, this rule is for glaciers too. And believe me there aren't only "snake" shaped glaciers. There are round, traiangular etc. glaciers.
