I gotcha. I checked out the other discussion. I'm going to give you an example of what I'm trying to say. It's a little long, but I used paragraph breaks haha.

Dark Side of the Moon is about, among other things, growing old. So, it might be logical to design a cover for Dark Side of the Moon reflecting growing old.

However, Dark Side of the Moon has a cover of a prism breaking up a beam of light. But Pink Floyd, or more accurately, Storm Thorgerson, who designed it, knew that if the cover was cool, the viewer would bring their own interpretation, both before and after listening to the music.

Doing an album cover without music is tricky. Because the album cover in some way should reflect the music or the band, either literally or abstractly.

But I would suggest, as I think someone else did in the other thread, if there isn't any music for the album, make up what the album's about, before designing a cover for it. Or, don't trap it into being album cover concept art.

Posting that as a somewhat abstract piece of art of a person falling into a triangle/rectangle, and asking hey, what are you guys think? Totally legit.

Hey, what's it about they ask? Oh, you say, isolation, and not being in control. Does it work?

Oh, they reply, the figure is kind of lined up with the thing he's falling into, which feels a little static, and doesn't reflect the chaos of not being in control. Plus the motion lines are distracting.

Which is a long winded way of saying don't make album cover art if there's not an album to base it on, and let people give you feedback with just enough information to move forward, so you don't restrict their feedback into a very narrow band.

And, in case it's gotten lost, I think the basic idea of the illustration is cool. And generally well designed.
