your track Transisco sounds really good. The only thing about it I might have changed is to put a little more detail into the kick drum and maybe a little less of the hats or to have put them in a subtle reverb. Rejuvenate also sounds good. On this track you might have brought the kick up more in the mix. This track could also use a cut in the low mids. Intelligent Life and Across the Globe are also great sounding, but like on the other song, a louder kick would have helped.
The tracks Plan B, Tunez, Reverse Tekniq seem to have weird compression going on like it is either over compressed or not compressed properly. If you have a track you would like me to master, drop me a link (I would do this for free; I need practice )
You got great musical work!
I would suggest putting your kicks up more in the mix so it is the loudest instrument in the mix. If you look at the rendered song’s wavefile or at a spectroanaylsis meter/graph this will become quite clear on how to check to see if the kick is the loudest instrument.
Hope this helps, and I hope you get something out of it.
