I want to point out that the version that got declined [1] definitely did not have any independent references to support notability [2] (and had it been accepted would probably have been nominated for deletion quickly).
The current version looks fine. Unfortunately reviewing drafts is a very thankless job (~90% of drafts are worthless) so there are never enough reviewers (speaking as an Wikipedia admin who used to review a lot of drafts). The backlog is definitely not something people are happy about, but it isn't easy to solve.
Also, having your drafts reviewed is actually not required. Once you have made 10 edits you can move the draft to the main article space yourself (or directly create articles). The reason why brand new users can't directly create articles is that whey they used to be able to, a ~third of all new articles ended up being deleted immediately because they were spam/gibberish/vandalism, which ends up both being a lot of work for reviewers, and very discouraging to those new users.
