Eastern Veil and building an image

My latest image project has been the Eastern Veil Nebula in narrowband. I shot the SII and OIII first, both binned 2x2 and with 20 min subexposures, followed by two nights of Ha, binned 1x1 also with 20 min subs. I used a custom variant of JPM's tonemapping (http://www.astroanarchy.blogspot.com/) to assemble the channels and then some more color tweaking once it was assembled. I put together a gif to show the process of the image build (Click to view the animation): 

And here is the final result. 10.67 hrs total integration time (SII: 8x1200, 2x2)(OIII: 8x1200, 2x2)(Ha: 16x1200, 1x1).
