First of all, welcome to the Guild Sokail. This is a nice first map. I like the texture and color palette you've chosen. The mountains look good as well. The forests could have been improved (in my opinion) by reducing the size of the texture you were working with so that the trees did not appear so large. Also, you can see where the seems of the land texture meet. You might want to go with a different land texture in the future (or at least add and blend in other textures on layers above it). Still, overall a nice first map.

Cheers,
