Wow those are absolutely gorgeous! I can't wait to see your version of the Ent-B/Lakota. The only thing that I never liked about them, was the fact that they were a White/Teal color. I would have much preferred them to have been a darker Grey and Blue like the other Excelsiors. You wouldn't have the spare time to maybe paint a Lakota styled Excelsior the same color as your NCC-2000 would you? 
.
Also, I noticed on the NCC-2000 that the stripes just below the Deflector are a neat little aztec pattern. They're fine as is, but if your intent is to get it as close to canon as possible, I just wanted to point out that the Stripes on the Excelsior in Star Trek VI were just solid stripes. Of course if you already knew that and you just wanted to spice it up, then disregard by observation lol.
Maybe in the future I'll do a B-type with the NCC color scheme, as I'm curious as to how that would look myself. ;)
As for the stripes, you're right. I didn't notice that. But I think I'll keep them as is; it helps make the ship look bigger.
great job you did forget the phaser banks on the under sinde of the engineering hull and on top of the shuttlebay
The four phaser turrets on the bottom of the engineering hull have been on my model all along. I've never seen an Excelsior studio model with phasers on the shuttle bay.
Thanks for the feedback, guys.
I'm pretty much done with the Enterprise B. I'll do all the spec maps once the total pack is done. Just the Lakota and the Mystery Treat are all that's left. Here are some renders.
