Aside from the water looking like a marble slab it looks okay. Posing and lighting look pretty solid.
I feel like you’ve fallen victim to your own model here Hauptmann, that water model is barely like real water, so much that even the in-game medium does not legitimize its usage, especially in this ‘spawn and forget’ fashion. The reflection angles are also off, in scenarios like these I’d recommend using gm_black_reflective, and taking a look at how reflections look like in similar reference pictures:
might also be worth darkening the edges of the riverbank and the bridge-post things so they look wet
Top section could stand on its own
This alone is a really nice shot, the bottom half just kinda doesn’t have enough going on and it throws the balance of the composition off.
Any links to download those horse models ? they look better compare to the ones from dark messiah.
