Okay this is the last one for now. It is an ART stamp, and I got the idea from a book - True Colours - the artist was Sarah Fishburn.
I used Ranger Spray ink for the background, and 2 pieces of stampboard for the main focus. I added alcohol inks to it, then stamped on top. It is fairly plain, but I think the stampboard speaks for itself, and is the focal point of the piece.
