Although not an accurate Moc of the two seen in ROTJ, the idea about Mon Calamari Cruisers are that not all are identical due to the builders regarding each one as a work of art. This started off first as an attempt to make a Rebel Assault Frigate but instead decided to make this instead.
I either didn't have time or couldn't be bothered to take new photos of the Rebel fighters, especially the X-Wing and so instead used what I had on hard drive.
This image didn't turn out as well as I had hoped, mainly because I'm not very good at doing explosions or even laser effects that are all absent from this one just as they are from the one up top. I sort of based this one on a scene from Battlestar Galactica.
