This is my old work (painted without the tablet. only with a mouse ). Drew this after played in Mass Effect 2. The background is not my (space). I found it among the wallpaper. I don't know who the author. I hope he will not mind
Probably about how awesome it would be to have biotics... and about how horrible it is that in this cool, advanced galaxy there exists something that is so close to the force, yet the Quarians get completely overlooked and can never have such awesome abilities. That's what I would be thinking if I was a Quarian. She is probably trying to summon some biotic spark for the zillionth time. That's why she is so sad.
Giving her internet history, I would not be surprised if she is fantasizing about what it would be like in a threesome with Garrus and FemShep. Tali always seemed more interested in people of over races rather than over Quarians and she gets along wonderfully with both and like wise with G and FS.
