Laj,
Oops, I almost let this one slip! Sorry man. Tuning in now.
Czentre - Very rich bass, made me feel like I was sitting beside a massive nuclear engine.
The 'drum' sounds in the 1:--2:00 range are hidden? Sounds like a click track left in the mix.. Although it's probably really low appreg. I'd either remove them or spice them up. Kinda nix's the smooth ambience of the tune.
Song picks up around 3:00, goes a different route, nice fake drop-out, swings the mood around a bit. The bg piano isn't in rythm with the beat, nor is the other sounds. Those 'drum' sounds are back around 5, piano slows down, but the beat does not... If I were to categorize the style, I would call it 'ambient noise', since there appears to be a lack of simbiance between the orchestral properties of the tune. But it is a nice effect, not really my style.
German Wind At The Bongo Bbq - I have a feeling there is a few samples you really like to use

Much more rythmic in the introduction. I might quiet down that break down with the false snare in between 2:20 and the next one around 2:40, it's a bit striking and obvious.
Possibly eq. the synth lead down a bit, distanced a bit far from the rest of the mix. Increase the overall bass value in this one, it gets a bit on the high side of piercing.
A little closer to 'techno', but slowed down to ambient I would say.
Streams - Got the whale effect running

For a trancey tune, that underlaying beat gets the heart pumping... Intention to throw a person into a thoughtful spasm? Neat effect, can't whine much about the mix, other than top side gets to be a bit much every now and then, might cut the ceiling a bit.
Keep in mind, Electronic is something EXTREMELY difficult for me to critique, source is electronic, samples, many many tracks, many things happening at the same time, so I don't usually comment on them. I liked these pieces, but it is not my genre of choice
