I do like your take so much better. For some reason I got the sense that JK wanted to just be done with the whole thing as there were so many loose or weird decisions. Like Felaine said - 'in search of a sandwich'? Reminds me of a line I heard somewhere about the war being lost for want of a shoe. Never cared for the "after battle" scenes nor for Snape dying from a snake bite (like he wouldn't have seen that coming!)
The art is breathtaking. Harry's tear, Severus soothing and longing hold on him, the Dark Mark breaking apart in the background...just wonderful work.
