First thoughts
1. Wow, Snyder has cranked up the muscle definition all the way up to 11. Some people thought he would tone down on it after MOS and after looking at the official pick but no, this is Snyder we are talking about, this is definitely the most cut we have seen Superman in live action. The new look might be indicative of Cavill's new physique for BvS but its definitely different from MOS. The definition in the legs looks really intense and now finally Superman has a decent set of abs. The abs on the MOS suit were criticized for looking fake and they seem to have addressed that, these look more realistic. It also seems like they have upgraded him to an eight pack as compared to merely a six pack in MOS.
Some people will think its too much but I think it looks great, I have commented in other posts that I want Snyder to go all out and make BvS more comic-booky and this definitely looks like a step in that direction. Superman in the artwork basically looks like an anatomy chart and Snyder has brought that to life here with the help of Cavill.
2. I still don't like the new belt. I preferred the MOS version.
3. The blue is not only brighter but a new shade entirely, atleast that is how it looks to me. Looks like a more inky blue to me.
4. I think the Superman fans who were worried that Snyder, a lifelong Batman fan would undermine Superman in this movie should take heart - Snyder's actually given Superman a very intimidating and alpha look, making his musculature and physical strength very "in your face" and over-emphasized. This should serve him well while facing off with Batman who would be wary of Superman and maybe even a little scared!
5. I think this might be one of those "POSED" leaked shots like the infamous shirtless pics from MOS which were actually shot by official stills photographer Clay Enos to look like paparazzi shots and then "leaked" to the media. I think this is a very good shot, frontally shot and with good color and clarity. I think this might have been released because they are going to shoot out in the open soon and they don't want the first in action look at the suit to be ******.
