Need critique for first map, and help with climate and biomes

[Hankrecords]

Just by looking at your map, I see a big problem.

I assume this is a map of one portion of the northern hemisphere, covering the equator to the north pole?
If yes, the pole is wrong. It should be either land or water, not both.

Ah, you're right. When I drew the map I imagined it covering from the equator to a little south from the pole, and have water and ice caps norh of the northernmost island. But then I forgot about it when I drew the latitude lines since they imply that the top corner of the map is the pole.

I'll have to fix it. Thank you
