Have you seen this:better than the crazy dreadlock halflings of 4e IMO
Over all, I am really liking the 5e art. Its not the "Bondage Gear" look of 3.x, nor is it the "ACTIONALLTHETIMEADHDD&DSQUIRREL!1" art of 4e/Pathfinder.
Of the WoTC editions, its probably my favorite. None of it stands out as to what I see as D&D still though.
That is still D&D to me. Nothing by WoTC has come close to inspiring as this one simple piece of art.
