It's been 4 years since starting and finishing this in Lightwave. I think it's probably my favorite mesh, but so large (at the time) that it was difficult to load into Lightwave's layout program. One of my favorite "Gundams" even if it's not in the UC timeline.
The mesh is "based" off of the Perfect Grade kit, with adjustments made to better suit the detail of the X100 frame Astray illustration from the Perfect Grade Strike kit -- which is actually a bit different in appearance, though ostensibly the same mobile suit.
The work on this was done Here Software: Lightwave 8.5 (modeler, renderer, Photoshop (post process)
