I think that you don't need a Nazi Mod, I would rather give you my Roley's Simple....on second thought, you need both. (xD no offence)
But, I checked your map, and I found these mistakes.
Distance Snap = Hardly any. You can make people lose the beat, because for some hit circles, it sounds like its in beat from the previous hits according to the spacing, but it wasn't.
Grid Snap = I recommend. Use this if you want a better allignment; you should.
You don't have to start a song from the beginning. It sounds rather ugly for this song (in my opinion, no offence).
BPM = Change to 132.134
Offset = Set to 3,873. Don't start the song from the beginning.
It seems that you end the map in the middle. I did that too. This song repeats itself a few times, no point of mapping the entire thing, well you shouldn't map the entire song for Easy, that is.
Slider Velocity is perfect.
Slider Tick Rate = I placed 2. 1 seems a bit slow for your map.
Oh, last thing for timing. Change the BPM, Offset, then in the bottom, click "Snap to new timing". "Use snap divisor" and the drop-down bar should not be faded now. Click the drop-down bar, and select 1/4 (blue ticks). Click "OK". Your beats should be in 1/4 timing now and should sound right. If its not, consider re-mapping the song my Offset suggestion.
Now, on to the beats itself:
BSD used for modding: 1/4
00:11:459 - Break - Remove. Its super-short anyway.
00:20:887 - Slider 7 - Doesn't sound as if it belongs there. Remake this slider, without the repeat, but with the same length.
00:24:295 - Circle 3, 4 - Holy crap, 2 hit circles, tooooo close to each other. Remove 4.
00:25:886 - Break- Add one.
00:29:975 - Circle 5, 6, 7 - They all should have a finish sound.
00:31:339 - Circle 8 - Remove.
00:56:785 - Slider 4 - Extend to 00:58:375
00:58:603 - Break - Add one.
To sum it up, fix the mistakes I pointed out, the BPM & Offset, and SNAP YOUR BEATS!
Of course, I also promised my own version of the song.
INSTRUCTIONS TO PUT UP MY VERSION OF THE SONG TO THE FOLDER (only if you need it, other wise, go and download the file.)
1) Save file in Program Files/osu!/songs/Dave Wise - Greenwood Village
2) Once downloaded in the folder, go to osu! (the game), search up for the song. There should be your difficulty and my version. If not, press f5 to refresh and see if it works.
Oh, and be sure to give me kudosu If some of the mistakes gets fixed, I will star this map.
