OMG finally done! This has given me so much trouble ._.
This took almost 6 hours of continuous working (minus a 20 minute tea break). Sculpting different parts aren't too hard, but putting them together is a nightmare. I keep breaking bulbasaur's vines when putting them to bulbasaur's body... and I really underestimate how hard it is to put things in a bottle with 1.5cm diameter opening x_x
Anyway, just so glad everythings done!
Everything is sculpted with Sculpey polymer clay, apart from the bottle which I bought from a shop. The bottle has an outer diameter of 3cm and bulbasaur is about 1cm tall.
