Your noteskin is good so far, however:
For some reason the 64th diagonal downleft note went out of proportion in size: https://raw.githubusercontent.com/ListenerJubatus/hardline-noteskin/master/DownLeft%20Tap%20Note%204x8%20(doubleres).png
I still have the original image though: http://i.imgur.com/TSV1iUA.png
Just replace the current downleft image with this image and it should be good to go.
EDIT: I noticed you increased the size of the arrows, which also increased the spacing between them. Maybe the 64th was forgotten...?
