I'm going to call them like I see them.
While I rarely use the coin command (mostly never) looking at that texture does kind of scream "redo me". I like where this re texting is going, but I have some issues with versions 4 and 5.
V4 has very defined ripples. Looks a little hypnotic. Maybe make them not go so far out from the coin and diffuse them a little so they look less like neon strings and more like waves.
V5 is very bright. The contrast of th characters makes them almost as illegible as the original texture especially because they'll be scrolling.
I like the pic DLPB posted, but that bg color is unflattering.
That's just my opinion so take it for what it's worth. I'm also terrible with graphics so I won't be offended if you shoot me down.
