One thing I would recommend is to change the format of your videos' titles. Since it's clear from your thumbnails and channel name that you're playing Clash of Clans, move the "Clash of Clans" to the end of the title, which will allow the more interesting parts to come first. For example: 'Clash of Clans | SO MUCH HP | All Pekka Shenanigans' becomes 'SO MUCH HP | All Pekka Shenanigans | Clash of Clans', which is a title that would interest me a hell of a lot more. You pointed out that you're working on your channel art, so there's not much to say in regards to that other than you need to create an icon that matches your banner or vice versa. I hope that you're also working on an outro screen in addition to an intro. As for the content of your videos, I cannot really give you any advice because you seem to doing well with it. I'm not particularly familiar with Clash of Clans, so I cannot really say if your commentary is any good, but you seem to know a lot and are very informative. Hope some of this helps!
