It is a great object to image Leo. I like the colour; though I think the data would work a little better with some luminance data. The blue stars look a little dark around the outsides and I have found this comes from using just Ha alone as your luminance layer. Apart from this the whole image is pleasing to view. Saturation looks about right in my opinion too.
Inspiring. The dust lanes, Bok globules, and some of the unexpected cloth-like drapery are beautiful. I like the idea of doing "close-up" extra-detailed shots of familiar but large objects.
