AEDM - Day 13 - Experimentation

I heard on the TV last week that the Northern Lights were seen farther South than is usual.  I took some photos back in May of Pike's Peak and I got to pondering how would one depict the Northern Lights in different mediums and I pondered different ways to handle the medium to portray this interesting effect in the Northern Sky.

I pulled up my Pike's Peak photos (OK, I was not trying to make sure I am doing this looking due North because I have no idea what direction I was facing when I took my photos), I just want to see if I can get the effect using my own reference photos....Here's one I did in my sketchbook with watercolor, gouache and white gel pen....The scanned image doesn't do this sketch justice, the Phthalo Blue for the night sky with Indigo painted wet into wet is stunning, if I do say so myself....It's very night time blue...I am having fun doing these.
