You got the clothing right, but I think Rand should be a bit broader and "rough-looking" (that would be texture work, probably). The face looks like he might have at the very start of the books, but I got the impression that he aged a LOT over the three years covered (well, it had been about three years when I lost track of the books; I think two came out since then, and another two are due out), but he didn't get the coat until halfway through the series, IIRC; a "younger" Rand would have "ruder" clothing, like that of the shepherd he was and not the apparently doomed leader he's become. But then again, you're running into the "fiction conundrum." EVERYONE will have their one vision of how the character should look, and you won't be able to please everyone. That considered, good work! :-)
