Well done, Michael. Plenty of detail to be seen in the Ha image, and the colourised one is very dark and moody.
The only advice I can offer is to crop the left-most 1/4 of the image so the dragons are more centered in the image. (Then again, use of negative space in terrestrial photography is a useful composition tool. So I'm all confused now...)
Oh, and Happy Friday!
Cheers,
