I see what you were trying to go for with the scenery thing but the color choice looks really...anyways maybe make your text less noticable and take off the border(?) I say try adding more depth and the blurring makes it really well look low quality. I know you tried to add flow doing the blurring but id say it might look better without it.
Depth-slight manipulation to create a 3d feel to a tag. 2 good ways that I know is 1) is to sharpen the focal and blurring the background by how far or close it is to the focal
2) also doing some burning and dodging so the lighter areas are the main focus while the darker areas should create less attention.
Heres something I made a LONG time ago (Maybe like...3 months ago?)

I kinda regret making the lines noticable...But anyways I used the lighting and scanlines to make some parts more noticable than others. And I do agree that its pretty bright...But well nothing I can do about that
The tag you made though is decent. I just think maybe some changes could make it even better
