looks fantastic, also there is a small difference between the end of the warpnacelle and that of the model.
Superb work!
Yeah, the model nacelle is just a touch shorter than the mesh you built's nacelle. Superb work, though.
Also, the phaser winglets are a bit larger on the physical model, and the curvature of the pylon is less smooth, evidenced by the conduit with the squares on it visible in the rectanglar holes running down to the nacelle.
Last thing I spotted is the bend in the cockpit windows, it's less centre-lined than your model... attaching a pic...
If we're nitpicking too much, just murder us a little.
