Man, some great stuff in this topic. Well, I got around to tryin to put some of it to the test in a new edit, and pixelation is successfully moved, so here it is:

Changed the arc of the headband, brightened up the whole painting on a separate levels layer, tried the smudge tool to imitate oil paint, and tried to make him more masculine, (mouth, scowl) while adjusting some of the edges (face, shoulder) with a wireframe trace overlay. Also tilted the sword to be more like Grimsane's edit, because I think it works better for composition, likewise painted some more sky to coverup the city, even though I didn't flatten it like he did. (I will though, don't worry, just didn't get to it.)
Here is the wireframe overlay for comparison, although I suppose a 50% transp transformed of orig would work as well:

Doesn't line up perfectly, but unsure if I should follow it too exactly.
GPick seems like a cool program to help with colors so might check it out, otherwise, still habitually color picking, but I think the colors here work well, especially in contrast to the darker version.
I have done that trick before, where you merge down, copy that to a new layer, and use it as a new base. It's way easy to check the progression, so I did it here, and I think it's improving. Good organized layers are evidence of good workflow, which I am trying to get better at. To not fall in love with work is something I've heard before, and experienced, especially in traditional painting. One little mistake and you have to paint over it. I've also had paintings lost in time, stolen or painted over entirely, so I've felt the struggle before, but that's part of the reason why I like digital painting. You can undo, and have infinite copies of it. Transform controls def offers a lot of freedom, hence the sword rotation. Def one of the things I don't miss about painting on canvas is making those colors, or trying to get a color back later, though appreciate the formal competency it has given me through practicing it.
Familiar with the work of Drew Struzan, and love his style. Those Star Wars posters for the prequel trilogy are great, and I have used for comp ref. Another great is John Alvin, don't think I'll ever get over his orig Bladerunner poster. I'm just wondering if the comp here is compelling enough to be comparable to that general style (not to their own work of course, they're masters.) Was experimenting with that dragon from the older version but can't seem to fit into a place that makes sense. Also thinking about using some kind of soul energy, also like the other version (the grey dude over the hero), but again hard to have a major element just to the side without detracting attention from the central focal point. Although, I could push the title up and have more vertical space, hmm.
Actually, after studying some of those posters I got some inspiration for a new more collagey comp, sketched it out on paper:
