I imagined something that might be nice, so I sketched it on a small canvas in photoshop and added it to my ideas folder. Later I imagined something different and drew a swamp.
I imaged during ancient Egypt with many different sizes of people from inbreeding. They said Atlas was a giant man, but Hercules they didn't give a size, but a Midget would look very strong if he was stronger then people imagined. So I made a Midget Hercules pushing the moon in a fantasy scene. I had to make it bigger a few times to get all the details I wanted. So the center was not redrawn, just the moon because light and dark started to mess up when enlarging the canvas.
This is what I saved while I was drawing, and decided to put it together to show how a person can start and create a digital drawing in Photoshop, or many other artist programs.
If looking at the PSD helps you learn how I draw then here is the download for this drawing in a zip file [link]
