PSE2019 Are there any overlays, or anything, that could somehow make this ebook cover more cohesive?

[BadStar]

I'm pretty satisfied with it, but are there any suggestions to just give it that one little finishing touch it needs? Thanks.

The small text on top and bottom:  put a black bar with 50% opacity behind the text.

[BadStar]

Thanks Glenn. I'll try it.

Perhaps add a drop shadow or other style to the text.

[BadStar]

Thanks Greg. The text already has a light dropshadow, but I'll experiment with other styles as well.
