It’s not that you should have a ready and massive collection to show, i and i’m sure a lot of others too here would love to see your current collection and the progress you make with it in future! It’s of course up to you when/if you feel comfortable showing your collection but i’m sure your collection certainly is ready to be shown already, it’s easy to get stuck in thought that you have to have more items or have more complete collection before showing it 
especially species collections always have something more to add so i think it’s quite common to put off showing them since there’s always the endless case of “just these items to get before making a collection thread”
