just downloaded both tracks.
1st has nice experimental grindy feeling. good work with all the atmo sounds in background and nice rough rhythmics in this one. production part of thing sounds good,. maybe some final touch on bottom as was said would be nice,.but i§m fine with how it is, now.

2nd one building slowly into big atmosphreic thing. very good using of background sounds again. nice broken beats and these percs sounds hypnotic. production part of thing doesnt sound the best to me. all the background sounds are very nicely done, but kick seems lacking little bit of top snap,. and also it all sounds little buried under kick., i think. feelin the vibe of this track, but i think you can go with better production here..
