This seems to be done with blood! ("those who are made of blood must shed it"). To me this awesome image is a fallen angel, a demon, or a spirit of nature - all blood and soul (and the peacock's tail turns to fire high above).
Peacock = pride: ridden with pride, Raskolnikow? I can call this interpretation traditional but Dostoevsky goes much deeper than any tradition and that's why he might be the world's most difficult author for the artists who try to illustrate him.
This creature is very quiet: tormented but quiet, even with the hell's blazes which rise above. What I see in Dostoevsky's Raskolnikow is an intrinsic internal struggle: a personality with an abyss within which goes from the hell to the heaven; a personality who has it all inside. Your Raskolnikow is sad, beautiful, androgynous and - first of all, integral. You gave him integrity: it can be due to the symbolism of your art because any symbol has integrity as its normal feature.
Well: maybe demons and angels are just a symbolic way of humanity to portray the complicated human beings.
(Compelling, gloomy, dark, disturbing - and I can't help but see Napoleon in it (well, Napoleon was Ronja's role model wasn't he?)
