Quite an interesting look Sean. A few thoughts:
- the extra bits at the ends of each cross arm look very "messy" to me, particularly with their proximity to the card border detail. I'm not sure those are entirely necessary.
- I'd definitely play a bit with some ways to get the cross to pop off the background more. Whether that's a shadow, glow, whatever. Your design is super complex and having too many of those details overlaying each other becomes hard to visually parse
- Can you give us a full res version of things? The green background is super high contrast (almost to a jaggy point), but the cross is looking blurred and indistinct. Think you need to get those a little closer in look, perhaps just a function of rendering out a higher resolution.
neat idea though, and seeing your progression is always interesting.
