Well ill be the first one, please check out my channel and tell me what you think, and be honest criticism is there for me to improve. Thanks.
Channel Design
I like your banner a lot, although the text could stand to be a bit bigger. It seems to get a bit lost in all the background. Avatar and playlist layout looks good and easy to find things. Titles look good, nothing deceptive etc.
Be consistent with custom thumbs. Some videos have them, some don't seem to. They could look a little better (the quality of the thumbs doesn't stand up to the banner quality), but if anything try to ensure all videos have them, if nothing else.
Personally, I found your 12 second intro to be too long. Some of the best intros I've seen have been 5 seconds or less. That's just my opinion (there's no right/wrong here). It was a good intro, catchy music, I just found it quite long and if I was having a marathon of your videos it would start to annoy me after a while.
Commentary
(From your most recent video) Missing in Action! That's a major problem for your channel right there. YouTube's ToS require commentary, and if you ever hope to partner in the future, you're going to need to remove all videos without commentary, and upload videos with you speaking over the video.
The above 'legalities' aside, I personally find no commentary FPS videos mean you're narrowing your audience. If you have GREAT commentary, someone who doesn't like BF3 might just stick around because the vocals are entertaining. Without it, your only hope is specifically someone who wants to see it.
(From a random Bioshock video) some stellar video quality here, nice to see the graphics amped up, but again - no commentary can damage your channel in the long run.
