I'm used to trying to paint efficiently, using as few layers as possible, keeping it down to between three and five layers. With this and the previous Iron Man painting, however, I'm playing with keeping every bit that could possibly be separate on it's own layer (in a similar fashion to some of my photography), and I find I am really enjoying the results.
But...wow. Twenty-eight layers.
Another Iron Man piece for that show next month. At this rate, I may just get a few more armour designs in.
