How big should pixel eggs be?

[tahbikat]

I think I made mine a bit small. Does anyone think they should be bigger, and how much bigger? At their current size I'm afraid I won't be able to add much detail. I'd also like to get their permanent size worked out in time for my new site's launch.

Also, what about the shape of them? Should their shape be more unique? Should they not even be eggs (since that's so overdone, really). My site is centered around magic, so I could use something other than eggs. Maybe magical orbs... I don't know. I'm horrible. :P

EDIT: Here's the current size:
