How to paint glass? Well, I don't know. But this is what I am thinking as I finish up this still life in my studio today:
SQUINT...get wrinkles while you paint to simplify the shapes
DRAWING...watch those perspective lines. Hmmmm.
VALUES...this is a painting close in values which is harder for the light effect. May need to push those cast shadows more.
EDGES. Do lost and found. Do soft and hard.
BALANCE Do rough paint. Do smooth paint.
Hang on to some of the original panel ground at all costs. (See light part of orange bottle.)
Spray some Chanel in studio to clear the air.
