909 train

so i did this yesterday after supper and i'm wondering, should i work on it for days/months and polish it to the max, or should i just release it as is? i find there is a really in your face feeling to the 4 hours version i might loose if i put on another 60-80 hours making every hat different, every 4 bars not repeating and so on, so, should i just say f**k it and upload it on iTunes/beatport/etc tonight or should i keep it in the need work folder and spend like 100 hours polishing it
