I think your comic is adorable. I felt the same way you did after going through ME3. The dark, desperate tone of the end depressed me much more than the sudden ending. Broke my heart to see my femshep all beat up.
Wow that is awesome! You depicted emotions so clearly! I also felt the same way, and frankly speaking I am feeling all this right now, because I've just finished the game with my second Shepard (its a femshep, romancing with Garrus), and you know, it is so sad to realize that the story is over... Oh. I am depressed a bit :(
