If any good space artists read this (unlikely, I know), then would they mind taking time out of their schedule to teach me how to create a simple nebula? I've read Alyn's walkthrough and I've tried damn near all the techniques he mentioned, but nothing seems to work for me.

DKF's "Heart", and a couple of things by Mr-Frenzy and Broke NL awoke something in me, a desire to create something as good as those.

So if anyone reads this and thinks they can help me out, tell me here or drop me a note. Any help is greatly appreciated. Thanks.
