Johanna Draper over at "Comics Worth Reading" (a great blog on comics) has a contest running for a male version of this awesome Adam Hughes "Women of the DC Universe" poster, seen here (featuring, from left to right, Catwoman, Oracle, Zatanna, Black Canary, Power Girl, Wonder Woman, Supergirl, Batwoman, Vixen, Poison Ivy, and Harley Quinn):

Here's my initial entry (featuring, from left to right: Oliver Queen, Green Arrow; Hal Jordan, Green Lantern; Querl Dox, Brainiac 5; Clark Kent, Superman; Bruce Wayne, Batman; Jason Todd, Robin (says Jeff, “emo style”); Wally West, Flash; John Stewart, Green Lantern):
A commenter noted that it wasn't as cohesive as the original women's poster, so I changed it a bit to have all of the men wearing black:
I'm not sure which I like better. All black is definitely more cohesive, I think the commenter was right, but the color one is more fun. I can't decide.
Besides the fact that I'm nowhere near the artist that Hughes is, I'm pretty happy with the results overall. I particularly like Oliver Queen's stance, look, and overall attitude. I'm least happy with Bruce Wayne, something about the whole figure just doesn't look quite right. I can't figure out what, though. And Brainiac's head bugs me, I think it needed to be squatter rather than so long and thin. Oh well, maybe I'm not so happy with it overall. This is the curse of the artist, every time we look at something we've done, all we see are the flaws.
Here's a closeup of Oliver Queen, so I can focus on something positive instead:

I do like the cohesive look of the monochrome suits, but you lose a LOT of detail in the all black version. What about using a dark charcoal grey instead of black? Or all white?
I thought about all white, but I dunno … they kinda looked weird. I can’t even say I am all that fond of John Stewart being in white in the first version.
I like it. Being a HUGE DC fan myself, I really like what you’ve done. A couple of comments. Perhaps if you made Bruce slouch a little more, he tends to hide his size when not in the cape and cowl. Also, Wally West has red hair and green eyes…Barry Allen was the blonde. Other than that, I really like the pic.
I personally preferred the coloured version, however if you’re looking for a lighter way to style the poster, could you try matching the Greek=Pantheon-esque nature of he women’s poster? Have the CD hero’s dressed in toga-like costume remeniscent of their associated Mythological counterparts?
