Is This Collage?

I haven't done very much collage, I just have trouble figuring out what should go together. So here is my attempt which has enough green on it for the Created Byhand Challenge. This is an 8 X 10 artist canvas board that I glopped gesso on and made some texture marks with a plastic spoon. When that was dry I scribbled Reeves water soluble wax pastels on and blended with a wet brush. The next step was colouring on the still wet canvas with Portfolio water soluble oil pastels, rubbed around with my finger then blended with a dry brush. I let that dry, then rubber stamped a couple of large background stamps, one music and the other script.
While this was drying I tried a Cuttlebug paint technique I read about somewhere on the internet. I put blobs and drizzles of paint on a piece of watercolour paper, placed another piece of watercolour paper over this and ran it through the Cuttlebug. I got 2 quite nice papers, but next time I think I'll just use a roller instead of the Cuttlebug, I don't like the risk of getting paint in my machine. When the paper was dry, I used my new Cuttlebug embossing folder from the Heritage set that I just got from Cherish The Thought yesterday. I sponged Walnut Stain Distress ink on the embossed areas to bring out the texture. My quote from Quietfire Design is stamped with Memento Rich Cocoa ink on a digital background I had leftover from the Tea Time ATCs. This was cut with Spellbinders Nestabilities Scalloped Oval and layered over a brown cardstock cut with the largest die from the Scalloped Oval set. The chipboard rectangles are cut with the Sizzix ATC die, dipped in coffee and the edges rolled until I got a nice distress look. They are stamped with some Michael's 79 cent stamps with Rich Cocoa ink and edged with Walnut Stain Distress ink. The white flower thingy is the back part of a button from Ruby Dog's Art House with a circle punched from scraps from the embossed painted paper and a brown half pearl in the centre.
