While I thought the smoke coming off the body was smart (and tragic, only part that got any response from me this chapter), the ending panels did feel rushed.
I think the 'fight' against Eren should've been its own chapter (with this one setting up the smoke, and maybe it ending with Eren screaming and turning all the Eldians on the hill into titans), chapter 139, and Isayama should've ended the series after the conflict on 140 (OCDer's rejoice).
Nonetheless, this has been my favorite manga by far. I find it hard to read other stuff since Isayama and Miura have spoiled me rotten when it comes to storytelling. Anyways... thoroughly enjoyed this ride, in spite of how it ends.
