First of all, sorry for my english
As you can see I made the original sketch by hand. In the attached file you can see all the steps in the creating process. Most of the time I sketch conventional on paper. The reason is, I'm much more quicker in this way. For this cyclops sketch I only needed 15 - 20 minutes (by ballpoint pen). Finally, I scan the sketch and upload the jpeg or png file to MyPaint.
Normally I work with 4 or 5 layers in MyPaint. I use one layer for the...
- sketch (This layer I only need for the primary color and the outlines. After its I delete it!)
(in the following order)
Very simple Isn't it?
Most of the time I draw the background in MyPaint but I also use another open source application (paint.net) for creating backgrounds when I use logos or fonts.
Hope this short turtorial was helpful.
