wooden sculpture

I thought that I would make a wooden house sculpture for office hall but I want to know what is the special requirement for that kind of atmosphere(office).

I am a sculpture artist and running a company Incredible Sculpture and I want to improve my art or skill so which topic should I remember during the making of face sculpture by wood?

Some people like wooden sculpture and some like metal so which one is most demandable in the market? Give me your personal opinion on this topic.

Evey this looks good and pretty in its natural color that's the reason, I want to know during the sculpting of any effigy, what color we should use?

Generally, there are lots of quality in wood but a sculpture should be long lasting. Many types of insect-like termite can decrease the beauty of any effigy so we should select only the best quality of wood, so which is the best wood for sculpting?
