Soo, the things I'm going to mention are just my personal preference, but I thought it might help you.
Firstly, the yellow is a bit strong indeed. You could use a gradient or a slightly less saturated yellow that is easier on the eyes. Otherwise people won't take the time to read the text, because the look away (I kinda had to strain myself to look at it for a longer time).
Secondly, the text. It's not centered, which annoys me a lot xD But I do think it will look better if you center it above the gaming controlers. I would center the subtitle 'gaming channel' as well. I would put the internet url in a different text box, it's very clear you just typed it in one. It would be more visually pleasing if you moved it away from the main title.
Lastly, the 'items' on your banner (social link icons, the leaves) look quite scattered and disjointed. You might want to give a bit more thought on where to place them.
Aaaand because I'm a horribly meddlesome person, here's an execution of how I would do it xD While staying within your concept, ofcourse.
PLEASE don't use this! It's bad quality. You're free to use it as an example though. What I did was center the text, bring down the social media icons and added the url to that corner. This puts all you linking info to one place. I also rearranged and added som of the leaves, to make them a bit more cohesive. I also braught down the saturation of the yellow, just a bit (like, -7). Hope this is helpful
