First of all, this is amazing and powerful. I want to shed tears for Legion and Tali and I've only looked at it for a few seconds. I feel that the "Halo" vibe you mentioned is a little apparent, but it's a good addition. Halo does a fantastic job about making you want to cry for the characters and the trauma they endure, and this picture needed that somber tone. I really love this picture, and it's really interesting that I was just thinking about writing a fic where this very pose takes place. It's like you read my mind! You have a great talent and I dearly hope you hone it and use it to make more amazing artwork. Keep up the fantastic work!
This is a very beautiful piece of work, especially in the context of the Mass Effect story. This picture really implies something incredibly sad (the Quarian extinction), and illustrates it much more emotionally than the game did (I kind of wish a scene like this was actually in the game) but enough about hypothetical(s).
What was Awesome: your choice of colors, I like the drab look, I guess I might have been tempting to go for high saturation colors similar to the game, but I'm glad you didn't. Taking the colors roughly shared by the two characters i.e. purple and dark purple, and exemplifying them really goes a long way in giving this picture character.
Amazing. I would like to hear more back story. It looks like legion does not care much; he is holding her in a significant way, but the flaps on his head are completely flat and down against his head (This bothers me a lot). But that is a very small thing compared to the awesomeness that is this painting.
Poor Legion. I think I'm one of the few that thought that Legion's death wasn't done very well, especially when you compare it to Mordin's death or Grunts almost death. The build up just wasn't there. Just a few lines of dialogue.
This one totally agrees. And I think that deaths should impact on the game - e.g. if you save Mordin, the dream shouldn't apear after the mission; or if Tali dies Garrus gets furious, or sth like that.
