Today I chose to work on a basic child character. I didn't want to complicated things with clothes and hair and such. I use this same body type for a lot of different characters so I wanted to create some reference for my generic little kid.
To test the accuracy of my drawings, I scanned all my poses into Photoshop and placed them on separate Photoshop layers one top of another. By turning the layers on and off it I could flip through the poses and see where there I had made mistakes.
Another cool thing is that once your are done, you can use the Photoshop Timeline window to make an animation. Select "Make Frames from Layers." Below is the resulting Photoshop animation. I then did an Export --> Save for Web and saved as a GIF (since I did the animation, it saves it as an animated GIF). Any anomalies in the drawings quickly become apparent when you string them together like this.
If you give this a try yourself please share your results in the comment section. Happy drawing!
