Okay so i think this whole setup generally looks pretty solid which is rare for someone in double figure subscriber count.
I'm not into the stuff you make the videos about purely cus i'm a gaming/sport freak but as a video perspective they are well put together and they look professional. I'd perhaps say show more enthusiasm and be more exciting in the way you deliver, if that makes any sense?
Could maybe tweak the thumbnails slightly so they're not so overcrowded and have the words/letters etc stand out more? That's really critical of me though because they're good.
Also one of the first things about your actual channel is there's like no featured video. I don't know if it's just me but I wanna see your best/favourite video straight off the bat when i click onto your channel... or a trailer or something. Just to keep the image looking professional and fresh.
Overall though, your channel is good. I'm picking out small bits i think could help you improve but generally, you're doing a great job. Promote yourself more and add some enthusiasm and i think you're onto a winner
