Thank you Steve and Doug for another enjoyable and educational show. The thing I appreciated more than anything was one of the simplest: which was to copy merge a number of layers without even selecting the layers first; it makes working so efficient. Also Steve's inexhaustible ability to recycle and re-purpose objects into other objects. The added glint on the bottom of spherical objects also adds that great element of realism. I could keep going but suffice it to say I am now itching to be more creative in my own images.
