Your banner is nice and colourful. Nudes at 200 isnt really that needed... but considering you are a gaming channel.. your banner doesnt help me know that you are a gaming channel and your icon is pretty nice.. pretty funny with the watermelon background lmao.
your thumbnail art is pretty good as well.
My only suggestion.. i watched the first couple minutes of your crash bandikoot game.. and first impressions... you have too much side jokes happening when you should just be focused on the game.. your commentary needs work in my opinion, unless youre purposely trying to come off as a jerk to your viewers? Your viewers and subs is what makes your channel grow, and for you to say you dont care what they think and so on.. its fine if your doing that on purpose.. if not, first impressions are youre just rude.
