I checked out "Time Traveller". I'm not an expert and my taste is my own (old school electronic isn't even my type of music), but here are a few of my thoughts. Also, you did a lot with this song and I'm only listing what I don't quite like, but there was a lot of good.
1) I'm not a big fan of the missing 8th note, I think it leaves it too empty
2) Try maybe a bit more reverb or sustain or something on the bass at the beginning
3) The 2 high notes that you can hear around seconds 54-55 and are repeated every few seconds bother me for some reason.
4) The transition at 1:49 seems a bit sudden? The transition at 3:06 is similar you could argue but for some reason it bothers me a lot less
5) The end is a bit too easy with just the volume going down.
