I like it, keep going you will only improve.
Some suggestions are to center all icons (e.g. vote icon/sniper weapon icon are not perfectly centered), fix some minor pixelation issues (e.g. team icon text font CLA/RVSF), avoid using 1 (use 2 or 3 instead) pixel borders as they look pixelated in-game especially when using white (e.g. numbers), re-save using GIMP to avoid the white pixel line issue (e.g. sniper scope crosshair), use paths to make selections/create icons for non-pixelated graphics, use deviantART and akimbo.in to host your work as the upload sites die rather quickly.
If I save a PNG from photoshop I have the same issue, so I merge everything on a transparent background and save as a new PSD, then re-open in GIMP and re-save as PNG. I have no clue why it happens in the game, but looks fine when viewed anywhere else.
