Hi there, and welcome to the Guild! The Saderan tut is a Guild classic and you've put it to good use. You seem to have the basic idea down, now it's just down to practice. The outer glow around the coastlines is a tad strong for my taste, but that's just personal preference. One thing I do note, however, is that you have some river violations going on right now. We have a sticky thread on this subject as it tends to be something a lot of beginners struggle with, have a look through at some point. You're certainly on the right path, keep at it!
