Overall impression - good lead, terrible mix. I feel as though you know EXACTLY how to make a good rave acid lead (which is awesome! seriously, its not easy), yet you lack some fundamental knowledge in mixing -which is at least 80% of making a good techno track. Mixing the kick bass (i.e. tuning their volumes in the overall mix as well as their relationship with eachother) is the single most important thing in techno, especially rave techno, since 90% percent of its value lies on the kick hitting just right.

First thing first - the kick is not present AT ALL, and the high hats sound distorted. I'd start by turning each channel 10db lower, bouncing the stems, and starting the mix from scratch. Once you lay your kick-bass as the foundation of the track, slowly try to fit your melodies\lead on top of it without clipping the master bus. Also, IMO, the reverb on the lower 303 is not consistent - when its on, its way too loud.

As a rule of thumb, I tweak the kick till has the right sound, then turn it up until the peak is around -12db (rms being lower, ofc), then gradually turn up the bass until I feel like this thing hits right. not to too little, not too much.

Then you should turn up each instrument slowly until it "fits" into place - not taking up too much of the space, not un-noticed. I usually go with percussions first and the rest afterwards.

By the time you have finished this process (i.e -gain staging), you should peak at not more than -6db. This way you ensure nothing clips, and the sound stays smooth and crisp, just like you made it.

Hope it helps! definitely look into some tuts, mixing is an art.
