D&D Map of an Underwater Trench || HD Version

Hi there! I drew this originally just wanting to practice painting a bird's eye view, but realized that this ended up looking a lot like the D&D maps we use in our own campaigns. It's been created, so why not let people get some use out of it! (Be aware that this is not formatted specifically as a DnD map for TV or print since it was created originally as an illustration.)

I accept tips, but please do NOT feel obligated to leave one! I just want people to enjoy my art within their means. :)
