I did this maquette for my best friend as a birthday present. As the Mos Eisley one, it was done in Styrofoam, cardboard and paper - painted in acrylics. Sorry for the low res of photos, they were taken on my old cellphone literally minutes before I gave it away.
I also realize the Great Pit of Carkoon looks like a certain part of human anatomy when viewed from above (and BELIEVE ME I have went through all of the location reference photos), but in the film you never see it from that angle.
Movie magic, what can I say...
