Banner looks good but the slogan doesn't really mold well with me, just my opinion
Your videos have great vocal audio and start off well and fast to keep the viewers attention. I would advise you to say in your video what your channel can do for the viewers or do that via your branding so that people understand your intend.
A review of mine would be appreciated - I run a channel that features a daily show of which highlights royalty free music pieces for project/video content creators like yourself. I try and pick variety and quality as well as use my unique 3D audio spectrum for viewer experience

Review of brand, video format and thumbnails would be nice!
