Larger update
New update. I have images back on the back. I know it’s dated, but I really like the retro look. Could change again or have 2 variants.
Been lurking this thread a bit, and I must say, this version is way better imo compared to the rest. In the version prior, the back seemed too vacant and empty, even with the text. And in the version before that, the images chosen for the back, I think, both “blended” and seemed out of place, if that makes sense. Here, the images posted on the back work way better, and plus the borders added adds more professionalism to it all.
The only nitpick I’d voice is that the text (the paragraph ones) in a few places is trying to fight for center stage against the background image (most notably in first and third image). It’s not a MAJOR issue, and hell, I’d use your covers as is, but my suggestion is to maybe have some kind of semi-transparent background behind the text. In other words, your text’s background could be black, but not solid black. Just faded and transparent enough so that you can see the background image and still have your text really pop out. Overall, really dig it!
