It's a nice list, but a bit more genealogy would improve it greatly.
Many of the oldest writing systems began as a loose collection of pictograms but became more abstract over time. Where to draw the line between different stages of their development is often an arbitrary decision, their continuity hidden by the sparseness of ancient records.
For example, all of the following scripts can be seen as different stages of, or variations within, the same writing system: Old Hanzi, Oracle Bone, Bronze, Han, and Seal. Some of them might even be seen as different "fonts" encoding more or less the same set of characters. Others such as the Khitan and Jurchen scripts were clearly influenced by the Chinese writing system. It's a big family of related scripts, and should be presented as such.
A similar lineage can be drawn across many middle-Eastern and near-Eastern scripts that influenced one other and the Latin alphabet.
Of course there's still a lot of disagreement about exactly which way the influences went, but if you paint the picture with a broad enough stroke, you should be able to accommodate most of the uncertainty.
