I think it looks nice. Very Alex Ross-ish with the the black and gray look and Ross type chest bat and utility belt. Cool choice for a subject as it's a popular and influential style for "The Dark Knight".
The buff Batman doesn't bother me at all. I think of him as being built like a very lean linebacker and about that same size. But I agree that posing these guys with other non DCD figures looks a tad off. Well, more than a tad really. But it's the physique to me that looks odd more than the height. The arms and legs are just huge compared to DML and SSC figures. I think they look fine as stand alone or posed with each other figures though.
By the by, according to the rapidly going out of date (Thanks, "Infinite Crisis")2005 DK "Encyclopedia of the DC Universe" Batman is 6'2" and Superman is 6'3" in current continuity. Both have been made shorter and taller at other times. Superman was 6'5" according to his "Secret Files" description back when "Our Worlds at War" was going on. Both are pretty big guys throughout late Silver and Modern Ages.
Still hate the boots which are the weakest part of Superman. The zippers are idiotic as they serve no purpose other than to ruin the figures profile. They are the solution to a non existent problem. I really would like to send whoever is in charge of this a "Cool Girl" boot sleave to show them how these should be done.
The pleather cape is pretty neat, again ala Ross. Could be longer I agree but still a neat design. Costume looks fine overall.
Not as nuts about the utility belt. We live in an era of "real" materials, cloth, leather, "pleather' etc.. It would be much nicer and entirely feasable to make these functional rather than solid. But the look is nice.
As I mentioned with DCD Superman, I'm probably not as critical as I could be. I've been waiting forty years for these figures so I'm kind of looking at this in the cup is half full sort of a way. Improvements can be made, but I've seen people pay more for customs (myself included) I would say are inferior to what DCD is doing. So, I'm kinda happy with them.
My only significant unhappiness was the worry that they were going to hurt the line with weak releases early on. But as long as they offer a "Batman" every time they offer a "Two Face" I think it will be okay. I want to see a lot more figures offered in this series.
