Emrah Elmasli is a Turkish concept artist who now resides in the UK, where he's done a ton of concept art for the last few games in the Fable series.
Here's a selection of his contributions, mostly taken from Fable III.
I've also thrown a few more in from some of Elmasli's other work, for trading card game companies. So if you see a giant man with an axe and think, "that doesn't look like someone from Fable", that's why.
To see more of Elmasli's work, head to his personal site.
