I may not be the greatest beatmapper in the world, but I like this music so I'll try something!
So,
1. You should make it clear somewhere that:
a) This music is from Super Smash Bros. Brawl
b) It's a remix of a music from Donkey Kong Country 2
2. 322 BPM? Personally, I think it's somewhere around 160. Offset may be around 886 ms.
3. I know it's Hard mode, but are the hitcircles supposed to be so small?
4. I think that a screenshot of Bramble Blast, the background in that level, thorns everywhere or something like this would be more fitting than Enguarde for the background.
5. Spacing seems kinda strange at a lot of places. Made worse by the tiny hitcircles.
6. I still don't know what's the correct name for the things you click.
7. The map could end a bit earlier, or aim for two loops.
8. The final part was hell. What.
I suggest you wait until someone more experienced (like Zerostarry) gives their opinions on this, though.
