I think it's the perfect poster to entice people into the glamorous world of Dwarf Fortress.
Needs more beards, mushroom wine, people covered in blood and vomit tracking more blood and vomit LITERALLY EVERYWHERE, and some guy who's been disemboweled just walking around with his intestines hanging out/is on fire and burning to death while pushing a wheelbarrow full of socks because he hasn't noticed yet to really portray "Dwarf Fortress".
Also, it would probably be better if the clothes these people were wearing at all looked like they belonged in the same time period as one another. You've got a Mad Max villain up top, an 80's-era Bond girl in the middle, a porno version of a gladiator a little below, then a typical fantasy dwarf on the bottom.
