First of. I agree with what you said about views in your channel intro. Watched a few video`s and gave you sub.
banner fine
Audio level fine, crisp, clear right level
From what i see everything is fine. Just numbers game now upload steady content build up your playlists. Take COD for example a tad over 7 million video`s atm on YouTube it`s a tough market that 1 for people to find your video`s.
1 thing you could add to each video`s description is a link to a playlist all that content type is in something like. "if you enjoyed this video check out my other COD video`s" (link to playlist) something like that.
