The tower will look bigger, you know where the water spawn is, could you make that mountain bigger, like the artist mountain I think I named it. Not all those mountains should be the same height, I would say two of those (the artist Mountain and another one probs near the high mountain castle) the other ones should be smaller. Also don't forget about the other side of the mountain. I know this is quick sketch so I am just reminding you and letting others know what will happen with the terrain.
