Bouganvilea prebonsai development

Hello all,
Just in order to post something, (this is my second posting) follow my small bougie, yet in a plastic pot.
This tree is in development since 2007, its height it 18 cm and the base is about 8 cm (two years on the ground 2005 - 2007)

The root system is not ok yet, I checked it this year and I decide to wait one more year, in order to put it in a bonsai pot. So, this year I will keep on working on the branch structure.

the pictures:
2007 one month after collecting;
2009 carving work and first styling;
2011 the leaves starting to grow, basic branch developed;
Thanks
Fox
