It looks good! I like the theme of the map. I do have a couple concerns:

I would try to move some of the level 3 lava to lv 4. There's a lot of lv 3 terrain. There isn't much incentive to fight in the lava area if it doesn't provide any height advantage over the lv 3 castle area.

Also, it looks like you accidentally deleted a grass 7-hex in the build instructions. There's an empty space in the middle of the map on lv 2.

There are a few other areas where the map looks like it could be structurally unsteady. The rock 24-hexes aren't held up my much and the lv 2 rock 7 hexes seem like they wouldn't stay upright
