Quite a few updates to post.
Firstly, the shuttle...
Modeling complete. Markings and livery added. Looking pretty good at this point. I am in two minds as to whether to texture it or not - the original miniature does not appear to be significantly weathered, so it may well do as it is.
The Ajax... Quite a bit of work done here. Textures tweaked, details added, extra lighting and glowing phaser emitters. Word from on high is that 'they' would not change a thing. Looks like it is pretty much ready to rock and roll. Will need to apply the changes from this version to the Pilot versions as well.
