Hey I checked out your channel and honestly, considering you're brand new, you're looking really good!
I think most people will agree with me that when we first started out our video/audio quality were probably terrible (I know mine was) and our channel's graphics were probably bad too! Your profile pic and banner are great and the only thing I'd recommend changing a little bit is to add a section under your channel trailer to display all your most recent uploads! It might not seem too useful when you only have a couple of uploads but it'll look great further down the line. You can also add little icons onto your banner to link to any social media you might have.
Your camera quality is fantastic by the way and I really like the music choice (though you might want to add what it is into your description). I'm not sure if it's royalty free or not, but personally I think it's a good habit to use royalty free music. I can recommend a few good channels to you, but if you're interested I'll send you a message since I'm new here, not sure if the rules allow me to post channels here!
Keep up the good work and good luck!
