I don't know if you're trying to rank this or not, but if you are - the song is too short to get ranked with a single difficulty. Drain time for 5*+ maps needs to be a minimum of 5 minutes, yours is only 3 minutes.
If you are going to try rank this, you're going to need a Normal, Hard, Insane and an Extra to fit the difficulty spread of the song.
Ohhh, so I should find GD or myself making the Diff if I wanted to ranked it. Thanks for the information
Missing genre/language in tags.

The hitsounds for your map doesn't really accurately reflect the song. Such as random assortments of claps and finishes without any sort of pattern.
Claps are used to showing snares and high pitched drums. Finishes and used sparingly for the climax of intense points and whistles are used to follow the main melody. This is also helped by the use of other sample sets. For example, The drum sample set can be used for sounds such as toms and kicks. These can't be heard using most custom skins however so I recommend going through the map again using the default skin and listening to what your hitsounds sound like.
If you also wish to use custom sounds inside your beatmap. A list of file names can be found in the forum below.
