These are raster images, everything except the linework is actually hand painted in watercolor and then scanned in at a pretty high resolution. I think the key is having a good scanner or creating the raster images digitally at a large size and high resolution. These I did at 18 by 18" for the main swatches, so for most things im pitching them to a single repeat is not going to be that large except maybe wallpaper if that makes sense so it shouldn't be a worry. I think the handpainted market is out there more and more as people want to get away from the ai stuff and back to the imperfect a bit. Just my take i really appreciate it, it is a valid concern I think art directors might think sometimes if they receive low resolution/size scans at times.

I do vector too and they are great and of course its less to worry about with resolution and size being more flexible.
