OK, I guess I wasn't clear. I realize that the current interface is purely (if insufficiently for my tastes) functional. So, it looks kinda dull. You're making it more exciting. No problem with that.
What I'm wondering is whether you're planning for the interface to (kinda) exist in the game world, or just be aesthetically pleasing but clearly the proverbial fourth wall. For instance, Fallout 1/2 had the interface done using 1950s-esque fonts & digit displays, and the quest log was the in-universe PipBoy Data Bracelet*. This might translate to the interface using different colors (purple borders for being a Rocket Star?) or the result of hitting "m" would look somewhat like your PCS.
*And there is the time in FO2 when the person giving you free drugs tells you outright not to push that "barter" button with all the wires & fuses, because he likes you and he's giving you the stuff for free. But that's clear fourth-wall breakage.
If it's just a prettier fourth wall, then your mockup is pretty good as-is. Might look into toning that white down and making room for the status effects, but otherwise seems good.
