I'm far from an expert, but I do occasionally buy original artwork. The sheer multitude of works you are displaying (more than one a day!) devalues what you are doing. It suggests that these can be churned out with relatively little effort.
If you are really posting this for other people, and not just yourself, try posting fewer pieces. If you had to pick the single best work from July, which one would it be? If nothing stands out to you, then how is a potential customer supposed to pick you out from the crowd of similar artists?
I personally like the Persistence of Structure series, but they're each pretty interchangeable.
