This is a clan symbol, but as I'm a General (I run my own Regiment), I chose the emblem and colors, although background had to be display (universal clan unifier, don't ask, it's a pride thing). Carmel, I like yours, except I can't say I love the brown. Not my color, but hey, the emblem is nice. I used to have champion as my emblem before I switched ranks and we restarted our Regiments.
I came up with this right towards when the game came out, and I was proud of myself because I made it up. If you can't tell, it is the weighted companion cube.
Valkyrie sword with a shield. Basic, but I like the feel it gives off. I've kinda adapted it to everything else as "my" logo as well, sometimes without the shield,
I think it reflects how I am in game. The swords (to me) show my up close, in your face style of attack. It also shows how sneaky I can also be. Strange thing is that I'm a pretty good sniper. Not something my avatar reflects other than the cross hair style background.
