Well

Making highly stilized pictures like this is of course easier than a well shaded pencil picture. But this has it were it needs it. I actually can't agree with acid-burn here, I thing the head is great here, the silhoutte has great proportions, the sword seems a bit sloppy in comparison.

The big black buildings, the composition of the main lines in the picture and also the pose seem really good.

Two things though: The "red" part is underplayed IMO. This is a stylized picture, and I think it needs bigger, more glowing eyes.

The other thing: I dunno if it is perhaps needed for something you have planned with the picture, but the line-construct in the background, with the... flagpole? It really seems off. I see that it might have started to keep the symmetry with the building on the other side of the picture, but it seems very strange and clashing with the assassin to me. Also, I keep thinking of golf when I see this.. flagpole? but that is most likely a problem only of my own.

good, good

its good, not bad atleast, the only thing thats bothering me is the head, its to long and round, unnatural, otherwise its good
