I'd imagine with how it seemed to suggest Homage was with Littlepip in one of the rooms on the side each made in style to a particular season, that Littlepip does come out of the capsule at times and she even might get visitors if they want to risk the dragon flames.
Considering a person was only meant to be in the capsule for a couple of months I'd imagine Littlepip would need to get out and eat and exercise at times. That of course means Spikes cave probably gets more visits then it ever had in two hundred years.
The only think I'd change, just aesthetics-wise, is the shape of the helmet. Perhaps make it a bit more... Nightmare-moon-ish? I tried to go for a slightly more stylized look in mine, simply because I liked it, even if it's not functional like it would be (way more connections at the front of the brain than the back, just because of what parts you would use when hooked up into a computer).
*nods* I went over it twice, is why. I had a good, rough outline, then kicked its opacity down and put a second, cleaner one on top, then deleted the first one. It's not as clean as the fat-stroke outlines I sometimes do, but it seemed to be a happy medium between looking more detailed and still looking clean.
