Another one of my digital drawings on sketchfu. Probably drawn in 2013 before the site closed down. A lot of this is done by using opacity and transparency. There were about seven sizes of pens on the website and a large colour palette and a colour picker and erasers that I think had a varied transparency.
When you do something like this you have to build up from a basic background, layering details, adding more and smaller detail as I go along.
Observation is important. I can excuse slight mistakes, but I try and be as accurate as possible.
I’m interested in astronomy so being able to draw from beautiful images is a real pleasure. I think this either came from a stock image, or somewhere like NASA or ESA, but it’s so long ago…
