The Phantom Of The Omega

So, many people have told me to play Mass Effect 2 and I've finally decided to do it - only to find out that I'm fascinated by turians in general and Garrus in particular.

You have to admit, this was asking to be done - if for fun only. The idea was stuck in my head since the first time I saw Garrus on the Normandy after his recruitment quest.
And Liara is the only one I found suitable for the role of Christine. Obviously, I tried to make this pic look like an official "Phantom of the Opera" poster - whether I've succeeded or not, is for you to decide.

Rant: Honestly, I'm proud of this one despite all the mistakes (there are many, I know - for instance, the asari has far too many tentacles on her head and I have no idea how a turian hand looks like up close, and I can't draw clothes - at all) - mainly because it's the first digital painting I've ever finished. I've made a lot of drawings on paper, but it was always in monochrome - so I don't know much about coloring, even more so of digital coloring...
I'm trying to learn though. Honestly.
Any feedback is welcome and appreciated.

P.S.: The characters are property of Bioware, I don't own them. (Wish I did though... At least one of them, for sure )

P.P.S.: Yes, I'm aware that his mask is on the wrong side. But so is the Phantom's mask on the original poster. Mirror. mirror.
