Here are some more Safari XC spike doodles, pretty loose and quick exercise. Trying some new methods... pen sketches that I photographed with my iPad, then used sketchbook pro on my iPad to add some color and shading.
Thanks David. Yeah, I like that method because it's really quick, especially with my iPad. The iPad camera is pretty clear and works well for taking quick snapshots of sketches and doodles, and cuts out the scanning process. Very quick and easy!
Welcome oxyzen. It looks like you have a good understanding of rendering. I would recommend refining some of the functional elements of your shoe, and adding some details like stitching always helps too. Nice start.
