A Special and Personal Painting

My Dad had a very distinctive and artistic signature.  I practiced copying it for years, not to use it, but because it was so unique.  Since he passed away, I've wanted to make a painting incorporating his signature and I've finally gotten around to it.  It's not finished yet, but I'll show the start and where it is now.  A 20"x20" stretched canvas, acrylic paints, matte medium, water, and a tiny bit of modeling paste for the signature.
