Ok, you ready for the criticisms? Hopefully they are as constructive as possible. I realize this is just a sample, but it is worth tossing a few things out there for when you do your first WIP post.
- Water - The water appears to be higher in the middle than the sides. It needs to be reversed.
- Forests - The right side of the forests are "empty" due to the filter you are using. Either lower the intensity of the effect or do away with it entirely.
- Mountains - The mountains appear to be floating over the land. They should be grounded more, no pun intended. Also they have a bit of a plateau look to them. Try "slicing" in to them more with many highs and lows. Particularly wherever there is a river or a pass through them. I would suggest a bit of a blend from the plains area into the mountains as well.
There you go. I hope that helps. Oh, and welcome to the forums!!
