My first world map - Feedback wanted

[Iggy]

Painted new land and started to paint it using the popular Sanderan tutorial by Tear. My current result is below;

The actual map is 6000 x 3000 pixels, imgur.com resized it to 3600 x 1800.

Let me start by addressing the map-o-phant in the room. There is one particular island that will look off when you at the map. The map is to be used in my fantasy novel, it's split into a ice frosted part and a volcanic part. I want to make the mountain on the latter part to look like a volcano but I don't know how yet. There might be more of such oddities later on. I am also not done with painting the land, the ocean looks not good enough for me too. Rivers and roads are not present because of the small scale of the map.

Any way, feel free to take pot shots, I mean, post critics.
