Flash unfortunately doesn't benefit your artwork
I'm not sure how beneficial it is to show your artwork with audio and panning. I would love to see this work in its full definition, not majorly compressed into a .swf. Flash at the file limits of NG will simply pixelate half of the beautiful lines and tones that I'm sure are present in your actual work.
Newgrounds has a brilliant Art Portal where a still of your work can be viewed by people that enjoy producing and critiquing eachothers artwork. Why not try there in future?
