Congratulations, good stuff, I like the avoidance of mere simple riffing. The suggestions I'd make are making the album shorter (25 to 30 minutes), optimizing track order and perhaps introducing more common motifs to make the album cohere better and/or introducing more melodic "hooks" (ironically, which may involve adding more simple riffing in, to provide a counterbalance to the general, angular note flurries) to help the listener recall the songs better.
