Ok, so i was thinking on me dressed the same way as Jake (The CO i used) glancing over a tactical table like the ones used to plan moves in a War, with miniatures and stuff (At least, that's how Hollywood portrays them, heh). Said miniatures can be AW units, for example. Color doesn't matter for those.
As for my gesture? I guess a serious expression would be kinda adequate judging how I took the events of this match
Draw Kit next to me looking at the table as well, with a smirk on his face (He enjoys seeing armies fall, regardless of which XD).
Why him? Well, mainly because he gave me advice in some turns, so it's a way to say thanks. But also because me alone in the pic would be kinda sad
Oh, and since i didn't have the chance to ask him how he wants to be portrayed, I hereby declare right now he's a Lynx for this pic
(But with a long tail and not the bobtail typical from lynxes)
The "camera" (The PoV of the pic) would be positioned in the table or behind it, and aiming at me. That way it shows both the table and its contents, plus me standing after it. You can play with the perspective.
