Thanks!, i made some changes according to the points you mentioned
I really like the world you've built with these silhouettes and I like the lighting on the moon. I've got some points:
- The moon should also reflect in the lake.
- The land-dinosaur is unrealistically big judging by the perspective.
- The difference between the dark silhouettes and bright sky is a bit harsh and could benefit from Anti-Aliasing (AA), but this can be tricky.
Great atmosphere in this!
