Normals were baked and adjusted with substance designer. Textured in photoshop and blender. Everything else was done in blender. Rendered with cycles
This seems very nice. I especially like the light and the atmosphere.
Thank you! I used a volumetric scatter added with a volumetric absorption shader to simulate a little dirty water. A big Backlight to make the light soft and some spotlights with wave textures to give it a more organic feel to it. Glad you like it 
beautiful render.
Yeah, this was a beautiful image… 
I’m almost expecting the fish to swim along… Are you planning on an animation? A short one?
Nice work.
Can’t see clearly in the pic but the bottom middle fin should actually be 2 fins.
Oh thank you! Yeah I am thinking about it but the render times with volumetrics in cycles would be stupid on my stystem. But maybe I’ll try it with eevee
Oh yeah you are right. I definitely fucked up on this one. Thank you!
Thank you!
I like this image! It looks really realistic! How did you do for the scales? Did you sculpt them or is it a texture?
Thank you! Honestly it is just an image from google images. I placed some parts of the texture in photoshop and then fixed the seams etc in blender. I used that finished color map to make a normal map in substance Designer which i mixed with the baked normal i got from the the sculpt. But the scales were just extracted from the color map. No sculpting there
Well it looks good! Thank you for the explanations
