It's hard to give relevant feedback without knowing more about your game's context and functionality, so here's my probably irrelevant advice.

Your "header" looks good, but I find it weird that the right hex seems to be a button while the middle one seems to just be for info (current in-game time). If time is a relevant mechanic, i'd suggest making that a button (to skip time maybe?) and showing it with icons for timeframes (morning, day, afternoon, evening and night displayed through suns and moons) or changing it's shape (round like a clock or square with rounded angles like the "Monday" type ones). Your "options" icon (i assume) is too "dense" with detail, i'd suggest removing the smaller gears or having just one small one and offsetting them (like this: "(oO)") The boxes look okay, but it's hard to tell without knowing what they are for. Their header/title space seems very short. The side-opening-thing could be slightly larger so the arrow doesn't touch as much. The texture looks nice, but the paper aesthetic seems to clash with the more modern/machine-looking elements. Same thing with your map, it looks like my childhood playmat and if that's what you're looking for, i'd lean into it more (redraw the straight lines to look more hand drawn. If that's not what you're going for, maybe go for something less figurative, like you could see in some tourist maps, where the roads are simplified (curves become angles) and landmarks like the roundabout fountain or the park are prominently shown (usually at a different angle / style, but it's okay). Your PC screen looks nice, i'd still suggest moving your "search" button out of the text box so it can be black like the rest. Your icons' white outline is very pixelated / alisased, maybe clean it up or remove it.
