On the easel now

Here are two detail images of the beginning stages of a large painting I have started recently.
Large for me is anything above 24 inches in either direction.

The subject is a scenic panorama of Blenheim Palace in Woodstock, Oxfordshire. I am using as reference a few shots I took on a recent trip to U.K.

This will end up being the first landscape I have created in over a decade. I started with the structure itself since that will be the most challenging.
