Whoa there, welcome back mate!!
I was hoping we`d not seen the last of you with that first acid release.
What have you been up ta?

As for the tune, nice bit of acid with a Underworld-ish feel to it.

I wouldn`t send this out just yet mate, I reckon you can touch it up a fair bit to get it ultra pro, which I know you are more than capable of.

Have you changed your studio set up, or monitor placement since the last stuff I heard back when you did your Acid label release?

There seems to be some issues in the bottom end, especially around the high bass and ever dangerouse 200hz area. There`s a real lack of clarity from about 200 down to 80 which I think needs adressing.
The top end "nose" of the kick should be roughly balanced to the level in temrs of DB and frequency emphasis as the hats to keep the groove balance going, and it isn`t at the mo.

Bloody hell, just got to the bit where the acid all really screams, what happened to tunes that did this ey?

Also the top end feels a little too thin and really floats out of the mix later on.

My advice.
Dig back into the bottom end.
I`d give a little more oomph to the kick somewhere around 75-85hz
And then again a little boost to the nose in the top end try a little boost somwhere between 3500-4500, post compression. Sounds odd but it will get that kick cutting through, and will match it to the hats.

I`d pull back the 200hz region from anything in the bottom end except the kick. A fairly sharp Q (but not too sharp) setting and 2 or 3db cut will do the trick.

And yeah, maybe a little more ratio on the sidechain compression for the bass (if you are using any), and pull back 75-85 on the bass to let the kick through.

The main 909 stuff in the top end just needs more presence. I`d say a little more top on the open hat (or a stronger low cut, and more volume added). Maybe a touch of stereo spread and some verb.
Or you can go down another route and route you main top end stuff to a bus, give it a touch of bitcrush for a smidge of harshness, and a touch of compression.
For acid I`d be more inclined to go the EQ route than the FX route.

all the rest should sit fine after that.

Nice screaming acid mate. And the vocal really works well, gives it that little epic touch.
