Well done. You obviously took a lot of time to think this out and I agree that this is the most scientifically plausible version of Tali out there. The main issue I have with the canon Tali is her long, flowing locks. Not much room under the helmet for all that. If it could grow at all, I imagine quarians would cut theirs when they're in a sterile environment. My two cents: I would have imagined Tali to look just a little less sickly than this, Quarians are weak immunologically, but I wouldn't think of them as a frail species (case in point, Kal'Reegar and Tali on many occasions), and would the tubes be necessary if she was already in a sealed, sterile environment? Just nitpicking. I don't think Bioware will give us a re-imagining of the quarian form in any future games, but if they do, I hope they consider this version.
