I share your love of smaller bonsai, and it can be challenging but so rewarding. Be aware that they can be addictive! A lot of people who have larger trees move towards smaller trees as they get older, the biggest trees can be harder to manage. I started with smaller ones, got into huge trees and came back round to the smaller guys again later. Here's a link to my thread about my little guys.
Here are some shots of a couple small pretty trees. Deshojo and dwarf apple. It's cold outside so nice to bring some happiness into the room... The apple is new to me, it's a true dwarf apple, not a crabapple. Looks like fun to me.
