I just realized how repetitive this song is. Must be hard to map 
That intro sounded like a bitch to time too.
Blue = design/minor issues. you do not have to change these if you don't want to.
Orange = moderate issues. it would be best if you change these.
Red = major issues. you need to change these
Maybe you could map up to 03:54:144? It fits better to end the map there to me.
01:43:567 (3) - This note is unsnapped. AIMod doesn't pick it up for some reason. Just snap it back onto the blue tick.
02:42:049 (8) - Add an extra repeat to this slider?
03:01:704 (1,1,1,1,1,1,1,1,1) - Im not too keen on this part. It feels pretty repetitive and doesn't look very appealing. There isn't much you could map to here though, So I guess you can keep this if you want.
Considering how repetitive of a song this is, you did a pretty good job. Gimme a ring when the other difficulties are done, and I'll have a look at those

- Timing looks fine for most of the song. the red timing section at 03:01.601 sounds a little off though. I would use Offset:181,612.
- The source should just be Touhou, Undefined Fantastic Object should go in the tags. Also, you only need Touhou in the source, so you should delete Touhou from the tags.
