hit100/hit100k and hit300/hit300g/hit300k should be clearly distinguishable from each other (see https://osu.ppy.sh/wiki/en/Ranking_Criteria/Skin_Set_List#hitburst-set for more details.)
Easiest way you could fix this is just pixelate the text 喝 for katu (100k/300k) and 激 for geki (300g) respectively, and replace your current skin elements.
Currently your elements are identical and since they are gameplay relevant, I believe this is required.
O true u are right. Sorry I'm still kinda new to skinning, I'll make the change when I'm back at pc
