Hey Crayon, welcome to the Guild, and congratulations on your first map here. Have some rep for including a map with your first post.

I am assuming you will eventually remove those pale hand-drawn lines, but I kinda hope you don't: I think they look really good with this style, and add extra interest.

Great job with the mountains; you've done a really good job with them. One suggestion to make at this stage: perhaps lower the opacity of the mountain lines, a bit. You could probably cut the layer's visibility down to, say, 70%, and let the colour and shadows do most of the work.

Overall, really impressed with your first map, and keen to see the next update. Also, why don't you tell us all a bit about yourself and this map?

THW
