Character concept art made with a combination of Blender, MyPaint and Gimp. I did it with the purpose of documenting all the process in a document and then sharing it online. Please download the image to see it in full resolution (2496×1800)!
As I said, I wrote about its creation workflow in a pdf, and here it is: A FOSS Concept Art Workflow [1,54MB]
Note: please link to the posts and not directly to the pdf, because I often update them, rename them and move them around my Google Drive, so your links could become dead. Thanks!
