For the CSR Custom Competition. Yes I did use references (I'll list them below) though I wasn't trying to get the drawing to match the reference. More of a quick look or two just to get an idea of what it looks like. I obviously need to work on my nebulae though :x
Galaxy: http://www.universe-beauty.com/albums/s ... tos-53.jpg
"Nebula" (I'm actually not sure whether the picture is of a nebula or not, but that's what I was trying to draw): http://coolinterestingstuff.com/wp-cont ... space1.jpg
Comet: I looked at several pictures, but it most closely matches this one http://www.astronomynotes.com/solarsys/west-big.gif
Planet: No reference, but I did have Jupiter in mind while drawing it.
