Too bright, cannot see the toris very well.

Try a more realistic attempt on blood, but i cant help you there, since i suck at C4D adn try using textures.

5/10

i edited it. its darker now. Feel free to comment.
C&C are greatly apreciated

Blood looks a little off.
6/10

Now this is much better than the original you had up. It is easier to see both of the tori's in the picture and there is a good balance between the amount of light to darkness in the picture.

Only thing is that the blood looks a bit weird, but thats probably the style you were going for.

9/10 only cause of the blood.

any suggestions to improve the blood?

Blood needs to be a darker shade of red, imo.

Also, I'd recommend making the background a bit darker, because you can barely see the black tori's head and the blue tori's hand and foot because they are the same (or nearly the same) color as the background.

That's just my two cents, though.

new piece of art...
