Venitian house underpainting mosaic

I’m totally loving the photo mosaic’s that can be made at Big Huge Labs. When I’m working on something it’s so exciting to see a visual record of how it is developing and emerging by lining the stages up like above. I’m still putting into practice what I learnt on the acrylic course, by under-painting before anything else. That was hard to bring myself to do since I’d meticulously traced it in order to keep the exact detail!
