First thing I've noticed is that the kick sample and your bass sound is really out of date in Trance. People normally use it as a mid bass rather the main sub one. Also, really look into either getting better drum packs or making better ones yourself. They really aren't that powerful.

Your first synth is quite loud compared to the rest of your mix. The chord progression you have as well does not make any sort of musical sense. It just sounds like its thrown out of random. Lastly, do your best to avoid those cheesy saw synths. That stuff is really old school. (Unless you wanted this track to sound old school!)

Keep at it man. Try to make better synths sounds next time!

you can reduce the data size by lowering the bitrate. while 320kbps is great, in most cases 128-192kbps will be fine and the drop in quality will be barely noticable. keep in mind also that fl studio (assuming that is what you are using) seems to over estimate the final size of mp3 files by 1-3mb

that being said, this definitely needs some remastering before 3:58 but you have something going. one of the components of each of your buildups seems to have a lot of very intense white noise in it. IMHO it is a little too intense. I also think that be bass needs something is a few places, perhaps just a little more stereo offset on the delay.

that being said, it is a great start. plenty of variation while maintaining a repetitiveness that makes it easy to add into a long set. also a great selection of samples.
