We create many kinds of illustrations, usually in the process of creating our other ads or graphics but sometimes on their own. These can be either raster files (pixel based images with a huge range of gradients and colors) or vector files (line based images with fewer colors). For logos and product branding like embroidered t-shirts, one would go with a vector based file, while image manipulation such as background removal will be raster based. We are experts at both and would love to hear what your project entails!
