Alrighty!
Look at all the things I have trouble drawing!
Large elliptic shapes? Check!
Water? Check!
Glass surfaces? Check!
Reflection on glass? Check!

Still, happy with the picture for several reasons: despite the overall shabbiness of line and shading, the picture somehow looks pretty good to me; also, it the first picture in ages to take less than 6-7 hours (which basically means I’ll have a chance to sleep for a couple hours this night, hurray!).
Also, I really like her mane “Interstellar”.

NATG Day 17 theme is drawing a pony lost at sea/drawing a pony drifting.
Can’t get any more lost-at-sea-ish than being on planet Miller and facing a colossal tidal wave rushing towards you at the speed of a Shinkansen.
