You have nice aligning curves in yours, but a few them aren't aligned as neatly which throws the viewer off. I tried to show it in the notes where I thought your curves are strong and where it could use improvement. Also, adding some lines in the creases can help identify where the arrow is curving. And careful with the arrowhead...I think you elongate the arrowhead too much. Hopefully this helps.
