Share a little about the materials, processes and techniques used to create this piece. See Lesson #4. Adding interference acrylic colours is an option, and personal preference. I used interference blue and gold in this piece, as final accents in the background, and a little bit in the Wolf too. I like the pizzaz and funk it brings to the final result :) Is the piece for sale? No What are you most proud of? Experimenting! I am always proud when I take risks, and trying something off-beat and different :) What advice would you give someone starting this project? Interference colours really should be used as a last layer. Because they are so transparent, and they are not cheap! So they work best over top other colours, and especially dark colours! This is one of the reasons why I chose to apply some accents in the charcoal powder covered areas. Also, I do suggest to use any funky colours sparingly ... they can easily overpower, so I try to use them for sophisticated accents.
