I've got some pics of the build here. it's a beta-build, so I was only trying to get it assembled, and as such it's got some gaps. I've written a critique of the model for the next revision.
Dorsal hull.
Ventral hull.
Forward hull.
Aft hull
In the first pic, you can see that the nacelles will splay if assembled correctly. I believe the problem is at the tips of the wings. If you tilt them in about 15 degrees they should be just fine. The edge piece(part "E") should be one solid piece. As it is with the parts in the middle it's too weak structurally to hold up the upper hull without buckling. I ended up cutting the center out and gluing the whole piece to an extra sheet of cardstock. The main upper hull piece(part "C") needs to have the rest of the "tail feathers" on it to match up with the concave piece(part "D") and the red lines need to be black. The tail fin's(part "I") edge can be a seperate piece; I cut it off the right and left sides of the tail and lamenated them onto several stacks of cardstock and then wrapped the edge around and trimmed it. It's more solid this way.
In the second pic, the tail(part "L") as printed was too concave and I added a crescent-shaped piece of grey in order to match up with the upper hull's rear end. This enabled the rear bulkhead(part "H") to attach more smoothly. The front two landing pads need to have the small rectangles added that face the centerpoint of the bottom. As it is, none of the edges of the ventral hull match up texture-wise. You can see in the picture which areas need to be corrected.
In the third pic, the windows need to be shifted over about 1/8-3/16 inches in order to clear the wings. As it is, if you match up the wings to the Bird of Prey marking, the wings end up covering a window. You can also see that the bridge(part "B") needs to be raised off the hull about 1/32 inches. The front of the engines(parts "1", "2", "3", and "4") might look better if they faded to a lighter color in the center
In the fourth pic, I trimmed the aft bulkhead(part "H") about an inch total. The rear of each engine(part "7") needs a black circle behind it and needs about 1/16 inches of thickness all the way around in order to match the studio model. Also, it couldn't hurt to add a metallic texture to the endcaps.
You shouldn't need to fix all of these, as there is a Bird of Prey decal that can be downloaded from Starship Modeler that one could apply on the bottom.
