This was fun! In fact, I think I just came up with a new character that needs a bit of script! :-)
First attempt, brilliant! Obviously could do with a few more bits and bobs but quality before quantity. You have enough good pieces to play about with quite merrily, rather than having five hundred pieces which are all crap and don't fit!
As for the music, you can never go far wrong with Scatman! Bit of Cotton Eye Joe, though next time, methinks! ;-)
It was enjoyed! Well done!
