I've just downloaded a drawing program called KRITA free on the internet. It combines raster graphics with SVG and seems fairly simple to use. You can import /design your own brushes, textures, patterns and masks etc. I wondered if any of you have used this program and what the results are like. It's the only system I've seen that allows raster and SVG layers.
It seems a pretty powerful program for a freebie and looks like speeding up progress on my current project by an awful lot!
