After running around all day (I bought a new bike!), I'm now listening to your songs, in particular, Kids, Janes and Up. My first thought is that the mixes are pretty cool overall. Now that that's out of the way, each song could use some personalization, i.e. some things in each some so set them apart from each other. There's not much jumping out at me to differentiate the tunes. Try some different effects on different parts of the vocals. Some creative (not necessarily super obvious) delay/verb here and there. Stuttery delays, maybe? I dunno, I'm just rambling here.
I guess what I'd like to hear more of would placement of some sounds into a space, via verb or delay or some other creative ambience. Eveything kind of sounds like they're coming from the same 'place' - not a panning issue, but an issue of depth. i hope this makes sense.
At :40 the lead falling bleep sound could use some delay, in my opinion, to stretch it out a little bit and let the sound pass into the background . keep the panning of the delay the same maybe, or opposite pan it...?
at 2:09 some 1/8th note delay could be neatl.
anyway, you might be getting the idea here...
This is something that I almost always find easier to discuss with voices as opposed to fingers on a keyboard.
Also, I really dig these tunes. And the mixes are good, but I think they could suit each some a little more personally. This is the kind of surprise that really makes my day.
