The first section ("Origins of Buddhism in SEA") could be filled out a bit more, although I'm not sure if you're planning on adding it to an existing section. If you wanted to add more detail, though, it might be interesting to write about methods of conversion, whether it was voluntary, etc. The "Political Power and Resistance" section would benefit from being broken up into shorter sections with clearer transitions between them, because currently it reads like a lot of different facts all running together. Wording like "some conflict" and "much tension" is vague and difficult to prove, so I would try to avoid that as well. At the end of that section self-emulation should be self-immolation. Overall you have a good variety of sources and your draft is very informative, especially the latter section.
