My advice is to be more selective about what you submit to Stock. 5 out of 20 is not a good enough acceptance ratio.
Carefully check your work BEFORE you upload. Compare your best work with other available Stock inventory. For more feedback, post 1 or 2 full sized images here, along with the reasons Stock rejected them— Technical/Quality issues, IP violation, Similar Content, etc... See links below for more details on what's expected.
