Yo my guy so in future if you want to link your channel in that way replace /channel/lilpiffy with /c/lilpiffy because youtube hasn't used the /channel format for a while now and those who have a custom url like yourself have to use /c.
Anyways overall your branding is good for your channel art but the branding of your channel seems like a bit of a mismatch to the look of your videos thumbnails.
It can be hard when just getting started to nail the thumbnails but my advice when it comes to thumbnails is to look at your thumbnail and consider if it stands out as you.
I personally use the same or similar fonts for all my thumbnails, it has changed a couple times but in terms of style my thumbnails match in a sense that you can tell they are from the same creator.
Consider using the same or a similar style of font that you see in your channel art or choose one font and try to stick to it for all your video thumbnails.
Your 2020 goals thumbnail is one that I would describe as a good one. Sure it actually has you in it and not all thumbnails need that but the font looks clean and it isn't a brightly coloured mess. Consider Colour as more a way to highlight something or catch the eye having too much colours can have a more negative effect.
Take this thumbnail for example. Overall I'd say it's a decent Thumbnail but a couple tweaks would help it a lot. Firstly I don't reccommend having words overlapping at all it looks untidy and cramped then also you've left lots of space in the top right. How would I change it? I'd move the gun to the right slightly so it takes up a little more of that top corner. I'd make the title of the game a little bigger since you could get away with that and I'd space the text out so that war doesn't overlap with the other words. I'd then decide on a primary colour like yellow or red to make the word war stand out since the gradient multi colour thing stands out but as more of an eyesore (no offense) since it doesn't match the tone of theme of the rest of the thumbnail, red by itself meanwhile would.
Here are the latest thumbnails on my channel they aren't always the most interesting but the are very clear and concise when it comes to getting across what the video is about. The font isn't always exactly the same but it is almost always bright yellow on a blurred background. I haven't always done this but since my return to uploading to the platform I learned a great deal about the importance of branding.
One last point I watched your channel trailer because it auto played and your audio balancing needs a little work, the music was too loud and it took my focus away from what you were saying was very distracting. I use music in my videos but only to compliment what I'm saying and it's usually at a much lower level to my voice but can still be heard in a more ambient way.
Hope you find any of these points useful if you want to get in touch on or outside this platform hit me up cause you're not the only channel of your kind that I know so I might know some interesting collaboration prospects for you through the people I know.
Have a fantabulous day!
