These are two recent sketches I created in The GIMP.
Futuristic War Vehicle
The mechanical contraption above was somewhat inspired by the vehicle in Aliens for those who have seen the movie. However, I didn’t reference anything when I drew it and was really intended as a GIMP test.
The above portrait of a witch was also a GIMP test. I experimented a lot with this working with brushes and colors and many of the tools within GIMP. The final result of the mosaic was due to a filter I applied to the image. The sketch wasn’t really all that good so no big loss.
