I included the 3.5" x 4.5" sketch along with the larger canvas. The bird measures 15" x 15" in this size, everything so much larger and because of so much work done on this already that I can see a lot more in the photo by now, this will allow for a lot more in the painting, this drawing already so much better than the sketch. I have to clean this up of excess chalk before painting and I just may redraw with a darker neutral stain. The greatest challenge here was dealing with high humidity affecting my well stretched canvas (doesn't bounce back normal too quickly right now), don't know if this condition will clear anytime soon, patience. In the meantime I have paint to continue mixing for this, ensuring I have enough on hand to complete this confidently. For brushes I have 2", 3", 2 1/4" Wide Flat bristle, and #10, #9, #5's Filberts for the majority if not all of the details. Thank you.
