By now we've all seen this picture
This is concept art for what will be most likely be used for a mid-transformation look, if anything at all. We already know Conners will slowly turn into the lizard. We've seen the Comic-Con stage of transformation (likely final stage). There is already a lot of hate for this. Aside from the normal trolls who wait to bag on anything from this film; there seems to be people that think this is a definite thing. This is not official, and remember concept art is a maybe thing.
This is concept art of Loki from Thor
This is the final look.
I really hope some people figure out that means almost nothing at the moment. There are stacks of different concepts and ideas, and a few are picked out to be worked on further. This is definitely one that got much more attention, but that still doesn't make it final.
