1) Uh… I’ve never really paid much attention.
If a 1,000 lbs horse poops 50 lbs a day, you’d think a much lighter pony would poop the equivalent of 5 lbs for every 100 lbs.
Without telling you my weight, certainly doesn’t feel like I poop that much a day. Seems like it should be somewhere between half and a quarter of that. I mean, we don’t eat a whole lot; few slices of pizza here and sandwich there. Obviously with ponies like Pinkie Pie who are liable to eat an entire cake, your mileage may vary.
2) You’re very sweet to say that. But I hardly call two hours on this while staring at the exact pose to be any real measure of drawing ability.
