Sounds good.
First, to correct you. The original song isn't actually from Touhou, it's a Touhou-related song made by an artist from the label 'Alstroemeria Records', I think it was Masayoshi Minoshima, with nomico doing the vocals. The song is called "Bad Apple!" and has an incredibly good PV (Promotional Video), check it out on Youtube.
To be honest, this sounds good. It doesn't sound fantastic, but then again I'm not a huge hardstyle fan. I hear very little of the original song in there, on top of that,
Still sounds good. I'm not too well-versed with music so I can't really tell you how to improve it. I give you 7/10 and 4/5, though.
