The image is far too dark. If I squint I can see crosses in the backround,but the middle ground (aka the rock) blends in with the backround! So while the angel is bright and the snakes melt into the picture, there's only 2 levels of contrast-incredibly bright or incredibly dark. You completly leave out normal light, middle tone,and normal dark. (Not the exact names, but you get the point. 5 elements of shading.)You can still have a dark picture but you need to even it out. There's halftone on the snakes and angel, but the rock and foreground should have some normal dark and halftone.
Hmmm it was sort of meant to be this way... I tried to make clear contrast between the angel and everything else. And didnt bother with the details and shading the rock so that the most attention would be on his face.
But you aren't the only one who didn't like it so I guess I failed with this idea ) I'll keep it in mind next time )
