I have participated in a scavenger hunt on WetCanvas for the last few years. Every 9 days we get a list of items to hunt for and sketch/paint. The current hunt is all animals. Here are a few that I have found either at the Suffolk County Farm or the Holtsville Ecology Center.
These may not be large/small scale paintings but the practice doing the scavenger hunts has really improved my sketching and painting abilities.
This group was done at the Suffolk County Farm in Yahpank.
These were done at the Holtsville Ecology Center.
