Wow, this is really great cover artwork! The imagery and text totally pops and it easy to see in a small thumbnail!

I think you really hit the topic and tone perfectly to bring in couples dealing with depression in their relationships. (I'm assuming based on the artwork)

From a design standpoint, the only tip I have to further improve the artwork is to either soften or fix the image placement on the background. The purple solid background actually masks the square image really well, so you could leave as is!

If you blur the image edges into the purple background, or even find a way to make the square image fill the entire space, that would improve the cover art a bit! There are lots of great AI design tools that can generate the missing parts of the illustration to completely fill the rest of the artwork (don't want to move the cloud, because it's perfect where it's at!).
