very nice work, I wish I had half that talent. I've built 3 of these so far, first one was all stock pieces with a lot of lights, but then after a lot of research found out the MPC's are too tall on the sides and many of the pieces are rather bland.
the second one I did surgery on the sidewalls and brought the height down some and added some greeblies. I've used a few of Shapeways pieces and made molds to duplicate for future builds, the 3D stuff is spendy.
I like using the add-on landing gear as well and continue to come up with mods that produce a better look than previous builds.
Yeah, I've got a closet full and sold one so far and hope to sell subsequent builds.
Number four, I shaved the push blocks and the ridges above the headlamp panels. saw a pic where they were almost un-noticeable and liked the look.
I wouldn't mind at all trying one with a set of your pieces, they're nice, very nice.
