Really enjoying the artwork and attention on making the designs workable. Well done indeed.
I never really had a problem with TAS shuttles as presented.
Sure, there are size discrepancies and such, but even latter day ST suffered that problem.
In fact, TAS never gave us the standard shuttlecraft from TOS, which might have been an easy way out to just duplicate an existing design.
I appreciate the variety TAS presented, when they didn't even have to. And personally the designs are fine by me. Even better, they didn't really screw TOO much with the established design aesthetics. You could still tell they were ST vessels, which is nice.
And now with your updates and revisions, it's great all over again.
