There is absolutely no similarity between the three pictures. The first one is a sculpt (and not a 100% accurate one) of the 2000 design. The middle one is fan art, as DURATOK stated. And the third is an official still from the trailer.
Nothing in common save that some incarnation of Godzilla is seen in each.
Is that the similarity you were going for? That they all contained some kind of Godzilla design? If it is, then yes, we see it just fine. If it wasn't, then you must enlighten us as to what exactly you're looking for because there's nothing there for us to see beyond different interpretations of Godzilla.
If you want to know what Godzilla's final design is going to look like, watch the Godzilla encounter footage again if you can find it. Or, watch the official trailer again. There is no similarity between the Godzilla from the trailer and the previous two images that you're displaying for us now save for a general shape and the fact that the name of the creature is the same.
The first one has Godzilla standing nearly perfectly upright with a slender neck and head and a triangular shaped body (thick lower to tiny upper). The second one is a very reptillian and almost mammalian take on Godzilla with rather poorly depicted teeth and a cobra hood-like neck (which I hate). The overall design is FAR too thin and much closer to Zilla than most fans want to believe. But if you look at it long enough and replace the head the similarity is quite obvious.
The third image of Godzilla from the trailer shows a creature with a very thick neck and a skull that sort of just leads right into it. Godzilla in the official trailer is also much bulkier overall than either of the previous two designs. We don't know yet exactly what his feet will look like, but if they're anything like the comic con sculptures then they'll more resemble an elephant's legs and feet than either of the other two images. Godzilla's spines are different in all three deisgns and share no similarities whatsoever.
So what were you trying to see? If you think you see something, then you might want to check and double check again because there is nothing between them that is "clearly" visible or so obvious that you can just as us "anyone else see it?"
