I love ArtRage for its realism and painting effect and will one day (God willing) use it for some experimentations. In the meantime, I find it much easier in Krita to get this marker effect look. I quickly improvised the legs on the fly, duplicated the legs layer and with another quick brush I put in the shading. For concept arts and thumbnailling, Krita is the best. I guess this explains it:
“From 2004 to 2009, Krita was strongly focusing on being a generic image manipulation/painting application in the style of Photoshop or GIMP. Since 2009, the focus is squarely on painting: the Krita community aims to make Krita the best painting application for cartoonists, illustrators, and concept artists.”
Last night before bed (as you can see the dark background) I did some quick test with one of Krita’s Ink brushes. 10-30 seconds each. Improvised on the fly.
