Initial Impression --

The Good - Thin blocks, Weak Blocks  (Also Found in Core's roadmap)

The Bad - Advocating for SPV mining , which is a problem exacerbated by their Validate Once proposal, and pushing off the many benefits of  Segwit till the end of the year

The Ugly - 3rd/4th Q 2016  adaptive rule for a block size limit that  heavily incentivizes those with better bandwidth which would drive miners from China to locations with better bandwidth and make many home mining operations obsolete because they cannot compete with the propagation times with larger operations who can afford better uplinks. There is no consideration for centralization concerns or the costs of nodes with this proposal which makes it a non-starter from the get go IMHO.
