Ford, my piece is in the rough. Look at the dude's left leg and arm. Compare the areas of high detail to the areas of low detail. The issue isn't one of tablets or photoshops, but of work.

Yes. I'm the only one doing this. I could draw every object, item and whatnot at twice the present resolution, and then scale them down, but I don't, because then I'd have to spend twice as long drawing them. All game icons are drawn at display resolution. As far as the "small pool of colors" is concerned, I think the problem is really that Haven uses a much too large pool of colors. Each object has it's own palette, horrible though it is. If I did this over again, I'd settle for like three or four main colors, and then use those for essentially everything. If you look at the piece you yourself posted, you can tell that it, really, uses only about three or four main colors. With that said, I admittedly do not like the style of any of the pieces you posted. Not arguing the relative proficiencies of the artists, but they're definitely not my cups of tea.
But I am a complete autodidact who hadn't drawn anything, really, before I started illustrating H&H. I'm learning new shit all the time.
