The only things I would really change for is make the gas masks contrast more with the background colors, either through making the background color darker, or making the mask less transparent. I would also change the picture used in the bottom gamepasses, theres too little of the corner showing so I would either show more of it, or not show any of it at all. Good work overall though, hope I don’t sound too nit-picky.
Try and expand on what you want the icons to represent. If another player saw these icons in game, would they quickly understand what purpose they may have? For example, if you wanted a game to have a shop or settings option, you would involve perhaps a trolley and machine part to represent that. Apart from that, try and fix the circle outline as it makes the icon quality not look the best compared to the inner design.
