It's pretty clearly very derivative fan work, don't you think? In fact, ten years ago I incorporated a great deal of the same imitative stuff into this that the hacks at
Discovery put into their "design," which is one of the reasons that I'm thoroughly unimpressed with what they've done.
I wasn't the first or the last fan artist to recombine bits of the Phase II and ST:TMP ships into the TOS Jefferies design - it really is a left-handed exercise. Frankly, I'm shocked that anyone would be paid for this kind of thing.
As far as fan work that's slightly more imaginative and well-done is concerned, I can recommend Madkoifish's Enterprise variation, which while still derivative has some very nice touches. Judging from the rear-view angle of the Discoprise I'm pretty sure the CG people working on it have seen this one as well.
