Learned a lot along the way. Firstly, spray paint goes bad. The red paint I used had been in the shed for quite some time, and had heaps of trouble getting an even coverage. The other colours were bought new and worked perfectly. I will try using coloured paper next time....
Secondly, do the face first. Since I started with the hat, and attached it, then had an issue with damage and had to redo it, I would definitely leave it till last. Trying to patch it up was not 100% successful. Also, trying to put the face on would be easier without the obstructions ;)
And here he is!!
