Possible Unused D-Rex Concept Art?

From what we've seen so far (lego sets + dem legs in the trailer), this certainly looks the part.

LEGO D. Rex, anyone?

So we know it is light in color.

^ In the trailer it looked turquoise with a cream-colored underside.

So Badass!

My problem with the design is that she looks too much like a Giganotosaurus with mini-Spinosaurus arms.  I really think D.rex will look a bit more like a mutant.  But it's a cool design nonetheless!
