CoRtALoS, I think your present avatar is alright but I thought your moving demon hunter avatar was pretty sweet. thebastardsword, I also like your avatar, though it's kind of small to look really cool. MOHAMED, your avatar has a great character but the quality is crappy so I don't rate it as high as other avatars. And TrongaMonga, your avatar, to me, doesn't really look to much like a Dark Archon but I can still see the resemblance.
I give coRtALoS' avatar a rating of 7/10, I give thebastardsword's avatar a 8/10, I give TrongaMonga's avatar a 8/10 because it looks cool despite not being totally distinguishable, and I give MOHAMED's avatar a 6/10.
Gummy_Demonz, I agree that an avatar with Spike shooting would probably be cooler than the one you have now, right now I give it a 5/10. And Marth I give your avatar a 9/10 simply because Scorpion is a badass and can do some pretty sweet combos on Mortal Kombat: Deadly Alliance.
