Puppetise, these look better than mine, and I'm ten years your senior, so I wouldn't sweat it. If your stuff looks this good now, you'll be in high demand by the time you're out of school. I'll say this, as far as eBay goes: presentation sometimes counts for a lot, regarding whether something sells, and for how much. Haven't seen your auctions but I know that less-desirable stuff can sometimes go for more than it ought to, if it's presented well. And of course there's building a reputation and all that.
But what do I know. I'm a snot-nosed college grad workin' for The Man.
