Oh man, it gets pretty crazy hey, like ~2:42! I think this is on getting close to the impossible, and I challenge anyone to complete just that section (looks cool in the editor timeline though!) And one more thing, I also found the spinner at 2:40 really short. It's really sudden, so unless you know the spinner's coming up, players will probably just miss it completely.
Your other spinners are fine I think. The one at the start is a great intro spinner, as with the end one.
Apart from that seemingly impossible section, this is a great beatmap for insane players (not me). It probably deserves a much higher difficulty rating, like 5 stars. There are some interesting beat patterns in there, and the timing is good. Some decent breaks are in place and I used the time to flex my hand/prep my mouse :P. Surprisingly, it's also not all that repetitive, probably because I was trying so hard to keep up. This is probably best played with no-fail on XD
