Hey Augustinas,
Welcome to the guild! I have seen stuff by you on dA and also in some products. A very unique and own flavor you've got there! I hope to see more maps from you in the near future.
As to the map depicted here: I wish we could see it in a better resolution, so that i could zoom in and look at the glorious details! As it stands, it is hard to see your art-sy symbols and adornments.
What i can definitely tell is that the sea doesn't work for me. It's too abstract, if that makes sense. It also feels quite flat. It doesn't say "sea" or "big water-surface" to me.
I like that the map is pretty colorful, and the mountains are nice.
