Well for a first beatmap its pretty nice. You seem to have a knack for it. The only thing is that the song can be somewhat repetitive, with all of the notes one beat apart. I didn't mind it too much, just saying that some people will feel that way. Now, things that should be fixed:
2:12:13 - The note following that repeating slider is not spaced close enough to the end of the slider. It should be right next to it, just like all of the other full beat notes.
3:44:64 - The beatspacing expands a bit here. The spacing suggests the notes are around 2 beats apart, when they're one. This might be acceptable, but I'd like to see them closer together.
3:46:71 - You should try to avoid notes on top of sliders. They can become very confusing. This is actually where I failed the song at.
4:34:55 and 4:39:60 - That first hitcircle in that stream is a few beats away from the rest of the stream, therefor it should have a much bigger gap.
4:43:71 - Place that 10 closer.
