I think I will continue to mix things up. Try a larger canvase here group of smaller canvase there. I have an interesting idea in regard to a large grouping of smaller canvas (a grouping of 18 two foot square canvas) that may prove to be interesting.
Thank you for the kind words in regard to the trees. I have had many requests to duplicate this piece. I have given consideration to createing a series of about 100 of these (same basic painting with different colors, etc...) but I don't know if this is a good idea or not.
