Bwah, this is wonderful!
You're right, i bet it's because it's relatively long and straight.

By the way, any chance to see wet mane Celestia or some Celestia in general?

I just thought it's kind of amusing, how dorky it is, compared to the wet mane Rarity traces that were so popular some time back. Considering we've already seen Twilight soaked in water in the first and second episodes.

I've thought of drawing Celestia a couple of times, but I can't really think of anything to draw that seems interesting.

Princess Celestia preening herself (or her sister Luna)
That's something i'd find interesting!
Actually, there aren't a lot of preening pictures, not to peak of ones involving the Princess.

Thanks!
Added to my to-do list, I guess.

I need to cut this thing down. It's like five pages long, mostly of links and random notes to myself. A lot of them I don't even understand anymore.

Oh, that's quite a bit xD
You should do those where you think it'd be the most fun for you to do!

eh. I don't really think drawing is much fun. Occasionally, but rarely.
I just like seeing something that looks alright come out, and the hope that it might amuse someone (failing that, that eventually I'll be able to and it was useful practice).

Meh, don't be too strict with yourself.
There are many drawings in your gallery that really brightened my day!
