Nice Town Jegol and welcome to the guild. I think your layout is very nice. You clearly picked up some good hints and techniques from Pyrandon's map ant tut. I really love your trees, both the look and the distrivution seems very natural to me.
On the crit side I think your green for the normal ground ares may be a little strong (over saturated). Also the shadows dont seem to be continuos. The keep had shadows on the towers but the walls have no shadow at all making them look a bit like they are painted on the ground. I think just sorting out those two things will make a big positive difference.
Welcome again and have a great time.
