Made the blue one first and found it was lacking any umph... so created the red/yellow one which I like a lot more...
Both on Fabriano 1264 Mixed Media paper.
The blue one colored with Prisma colored pencils. Interior sections with US ArtQuest Mica colors Antique Bronze then Macro Pearl.
The red/yellow with Inktense w/c pencils then shadowed with a Zig Writer.
