I stand by my comments based on the poster, even more so now that we've seen it in other lighting and angles, the poster portrait does not depict this design at it's best, and Toho should have gone with a different angle.
Between the trailer, the official photo and the Sakai sculpt photos, I'm sold on Shin Gojira and he's actually in my top 5 Godzilla designs.
Like most, the unique details about him, muscle textures and such, coupled with the Attack on Titan designs and very different face made me fear when his full body was revealed, it would hardly resemble Godzilla. Then we got the leaks, which showed more muscle and bone like patterns, which made me think I was right, and the limited view made proportions look bad.
Now we get the trailer and all these product photos and a clear look, and all the parts that seemed indicative of a radical redesign pretty much end at his chest and actually don't seem as radical in the grand scheme. I also see traits of the '54 suit and puppet and the '84 suit, my top 2 favorite designs. Mixed with that, I've always enjoyed the look of lava and the red glow mixed into his skin looks really cool.
