A general comment, I think viewing 1-17, i get a feeling that, for what you are trying to do, u need either an interesting subject, or if indeed abstract, i'd prefer something striking, out of the ordinary or thought provoking. Some of the shots, seem more like you capture bit-parts of some common daily objects to pass off as (i presume, correct me if i'm wrong) "abstracts". Being random is one thing, but within randomness, i still would like to see some thoughts going into the shots, otherwise your randomness is point-and-shoot at best.
