I think it looks good, but the images kinda don’t match. What I mean is you have some vector images and some more detailed images. I would suggest looking on flaticon for vectors if you need them. Also, the close button needs a little more detail because it looks off with everything else that has shading. Lastly, what program do you use?
@CottonCandyInc I agree, they don’t match and i’m pretty sure some of them were found off the internet. I think you should stick with the style in the guns section, it looks like a clean design.
I think it was brought up earlier, but the images don’t match up. The UI is rather simple, so I think a simple drawing for each icon (like the hat icon) would be the best route to go. Forego the background images as well like the one shown in the transportation button.
Other improvements would be to make sure you’re properly utilizing the area of each button. For example, the morphs image feels quite empty while the coins button feels too cramped.
Personally i wouldn’t add that white bevel piece on top of Shop. It looks like a scrolling frame. I would recommend making it smaller. Everything else looks good.
I don’t relish the pictures, however I think the GUI is nicely designed. I would abstract those white bevels too, it might make the GUI look preponderant. They just look malapropos.
Spacing might improve readability. I’d give the type some room. Between it and the edges of the buttons and between it and the images. Try and keep the gaps/margin width consistent. Some images take up more space visually than others - a consistent source for the icons would help with that.
