Hello! And crit request

[Piotr Jasielski]

First issue would be perspective, you can find some tutorials regarding this matter on youtube. Second thing is the landscape itself - rivers usually flow in valleys, if you have a massive hill on the left side it would be more natural to have one on the right as well. Remember it's the river that carves valleys, not the other way around. Third thing - composition - you can also find some tutorials on the internet. It would be probably the best to apply the rule of thirds and place birds near the village as these things seem to be focal points.

Also if you want something ominous, it would be better to go with less saturated, darker colors. Best thing to do is to study some photos and learn from it.
