First of all, I had to say that when I saw the title, and then saw the drawing, my first thought was "aaaah, I see. Ginny is the one-eyed crone, and they're doing this behind her back (so to speak). Then I realized that you can also consider it a literal "Oh, they're behind the statue of..." nah! Ginny's the crone!
Okay, so my list of gushing:
First off, you know I simply adore you,and everything you do! Seriously, I would sneak up and steal away every one of your drawings if I lived closer.
This one, however, is just amazing. I don't know if you'd consider trading or selling it? (Name your poison, I can draw you anything... no, really. Anything! Want Harry and Snape and Luna and "that guy?" you got it!)
I love how you've used the compliments. All that blue with the orange of the "real life." The way you've divided the page, giving so much more "real estate" to the cool and hidden parts, and then this sliver of warmth. I know just how hard it is to push anything that warm into the background and bring anything that cool into the foreground in something like this, and you've MANAGED IT!!
Just amazizng, and really really technically fantastic.
If we were in a class, and I was running a critique, of the ones that have been posted so far, this one would have captured me and I would have given it the lion's share of the attention.
