I took a quick look, but I’ll admit I’m not the person to ask since I’m not into dubstep or anything “minimal”.
I think it’s cool you want feedback in order to improve, but I’ll tell you to also look at the hits/listens/downloads also as an indicator. I will post a mix or blog and not see any comments, but see plenty of hits. That does speak to me.
Post your mixes as entries in the music section here. I also suggest you seeknout a dubstep message board or facebook group where you can post yor mixes and ask for feedbak. Perhaps try submitting your mixes to online shows you like. See if they will play you as a guest.
