Oekaki... difficult stuff. Looks great! I like her expression... it's very Cortana.
I don't know if this would make the work look too "busy" (or even if it's possible), but maybe add a few transparent, vertical lines of code like she has in the game. If done correctly, I'm sure it would look excellent. Maybe add a simple background as well?
Bah, that's just little stuff though. It still looks really good.
"Is my species of consequence to you now, Mustang? Did you really want my position that badly? Although I can appreciate the vanity of ambition, you should have spent more time planing. Even if you had somehow pulled this off, the counsil would have found you out, and they'd never let an assassin back into their fold." - Pride, FullMetal Alchemist
Admittedly, I don't like the Halo series very much. But your artwork of it is a different matter. You seem to be able to draw characters that ooze with style.
As for Dipstikk's art, he already knows how much I love his artworks
“Also, we don't need no Jacob to gay this place up. We have officially won the award for the forum with a highest proportion of gay members whilst not being themed about poojabbing, cowboys or Kylie.” - Nate
