Right now the whole thing looks like they are normal ground tiles with a white/blue palette. It doesn't scream "I'm made out of snow and ice"
I would give the sides bigger cuts, as if it were an iceberg that tore from some land or something. And I'd up the contrast and saturation of some colors to make it look more icy.
The tiles dont look repetitive, so I guess you did a good job, though they look rather flat.
The character itself doesn't read that well, though it improved from what you had at first.
Also I'm not really a fan of those black/dark blue outlines on it. While it works making the character stand out, I think the whole focus gets shifted to it. I'd make it lighter.
But that might be just me.
Good luck with further updates
(where's me shurikens? I can smell em dammit!)
I'm pretty sure you get them once you reach the 320 posts... or so I recall
