You are showing a screenshot from a phone? That means channel art space is very tight.
It seems a bit busy. A lot of objects are shown. Also the text is somehow lost amongst all the objects.
You may want to consider what you think is most important. Is your channel name important to be shown? If so, it should not be crowded by so many objects?
Are the gems more important to show? Then some other objects may have to go.
And your profile photo is going to be very hard for most people to see or read. It is crowded with objects.
Maybe try to narrow it down and be more selective?
