#ArtAdventCalendar is averaging ~400 posts per day so we'll be at a minimum 10,000 images posted by the end of the event. That's a full 10% of the entire collection of the National Gallery of Canada. I expect as more people join we'll have closer to 12-15k.

#ArtAdventCalendar while I paint a lot of portraits, occasionally I’ll branch out to other subjects. This is a scene of rolling hills and snow in the prairies somewhere along the QEII highway in Alberta. 26x48” #oilpainting #Art

Red sky at night, shepherd's delight.

For day 6 of #ArtAdventCalendar I present this painting of the Horsehead Nebula in Orion. The original was done with acrylics in 1996. This version has been digitally embellished somewhat.
