Ok so I had a second listen just to be sure. This is a really great song, good tension and release. I will give my feedback on the one part I'm not sure about though: the intro bars. Their is something that doesn't quite groove here for my taste, that might be a thing you are doing for tension and release with this stumbling motion before it really gets going. I think you could do with losing the clap in it and instead have a clap fill just before the kick drum enters and then put in the clap.

I can never bypass a topic with 'acid' in the the title.

I like the feeling of the song. I thought the build up of the song was a bit too quick, but yeah, it's a radio edit. I like the arrangement of 'The Caustic Mix' better.

The vocal snippets in the begining are great (they are vocal snippets, are they?)

The filtered synths stabs are great and they give the song its nice groove.

The acid sounds are a bit too dry for me, I guess they could use a bit of reverb (only top end, otherwise the mix will get muddy).

This song contains everything to be called proper acid house, the mix just needs a little work.

Here you can check out some of my acid techno but please don't feel obliged:
