They all take about 15 to 30 mins depending on the detail, number of colors, and number of sketches I go through before I am happy. I can't tell you how long each one took because I have drawn so many.
Thanks! The weather in Georgia is very bipolar. It was sunny when I took the photo and pored an hour later. I just have to pace when I take my photos. The moment there is a bit of sun I am out side taking them.
