I never thought about it before arran but you're right, the monkey sketch would make for an interesting model. If I model it though, it will be a loooooooong while. I still want to finish my ninja model I started for the last competition and my Rodney Robot model I did a while back. Most of the houses I'm modeling now will eventually make up a neighborhood scene I'm doing and that will take a while to.
P.S. If anyone wants to model the monkey (which would definitely be pretty cool), I can send you an electronic copy. Just keep in mind that I sketched it from a t-shirt. I didn't come up with the concept.
Don't be satisfied with what you can do but rather strive to do the things you can't do!
