I just came across this map

it looks great for your first map!

I would say that the mountains look a little too different from the rest of the map, them seem to really stick out from afar

the texture of the ocean is nice, but you should change the colors up in the ocean...try to give it some life

I do like the way the coastal lines look, and your color palette.

I think whats really missing is a compass, a border and some labels.
I don't know what you're using this for, or if you need or want those things but that's what i think is really missing from this map

Overall job well done!
