The first track is weird, but in a nice way, surrealistic atmosphere. What really bugs me though is that there IS NOT SUB in the wobble, it's missing the essence of dub(step) and misses a lot of power. Could be fixed easily I think, just layer a sine wave under it or EQ low in the wobble...?
The second track I wouldn't call dubstep, it's more slow electro that reminds me of Mr. Oizo etc. Finally there is some sub now, in the kick

. I like this mix, and it's in the same strange minimalist atmosphere. There could be a nice melody on top I think.
