Eh, not really. The Garrus/Tali thing was inserted as comic relief and only occurs if you do NOT romance either Tali (as M!Shep) or Garrus (as F!Shep). It was kinda a bad joke in my opinion, since the two aren't really romantically compatible as their dialogue becomes out of character and sophomoric. But it got "Lolz", so BioWare ran with it.
A very sensuous Tali, which is nice to see, because it's so hard to get right. I think it's because her face is always covered. But you've managed it nicely here, conveying her desire with body language and the tilt of the head. The colours are bright and delicious, and the reflection of Shepard in her helmet is a great touch.
