Okay so here is a few remark of mine:
The skin looks pretty ok at first but the more i look it, more and more bad things i found.
-First, you use the same picture for a lot of elements, like: You used the same picture for the ranking panel, for the pause overlay, for the menu buttons, and for the selection mode.
-Second, the hitcircle looks a bit off for me, i dont know that its intended or not, i'm gonna mention it just in case:

-Third, the edges of the inputoverlay's glow is cut down, it looks a bit poor.
-The score-x is squeezed, it looks weird.
-The skip button is a bit low quality in resolution but it's not that bad.
-The miss is too small.
+1: I personally dont like the font, and it could be a lot nicer if you were using more fonts in my opinion, thats not really a criticism, its more like a personal preference.
But dont worry, there is a lot of things that i like:
-I absolutely LOVE the look of that hitcircle, well except for the problem i mentioned.
-I absolutely LOVE the Hitsounds, good choices.
-The cursor is dope.
-The general looks are ok.
I hope that this little rewiew help. All i can say after that, good work, but consider looking at those things that i mentioned in the first section. Keep up the good work, piece.
