I feel like this would be a lot better without the chromatic aberration. The bold, black lines are pretty much the core of this piece, but the red and blue offsets seriously detract from that. I'm trying to focus on the lines individually to see exactly how you painted them, but I can't, because the red and blue get in the way. A picture shouldn't be difficult to look at, but this one is.
Compare to the picture you linked in the "artist's comments" section. It's very good, very easy to look at, it has a bold impact, just like what you're going for with this Ezio picture. With all other things being equal, that one is not quite as good as this one. But with the silly aberration, this Ezio picture just doesn't stand up to it.
Unless I'm supposed to be looking at this through red/blue 3D glasses, in which case I retract all previous statements.
In any case, do you have a non-filtered version I can see?
