You can not upload files directly to osu!!, you need to upload them to a service like mega, mediafire or gdrive and then provide their link (just look up on google how to get to the links for the file hosters, but usually its some right-click sub menu). ALternatively you can also send them to me via discord if you have that. RockRoller#1909
Hmm, so I assume one of the problematic areas are the white outlines which seem blurry? This actually doesnt have anything to do with you exporting the thing wrongly, its just that it actually is low quality in your psd file. It looks like you drew them with the brush or something, while you really should be using the rectangle or line tool
ahh thanks!, one more question though. do I have to resize any of my files to 1920 by 1080 cause the one I sent the screenshots with arent osk. because I dont have the Skin finish would making it a osk. change the res at all??
