Here’s how my vectory dragon is progressing. Doing big chunks of shading inside the lines is tricky. However, vector drawing makes scales and spikes easy! Draw a few, copy and paste over and over, and you’re done! I’m resizing spikes and scales a little as I go, so they don’t look too obviously copied.
It’s still very rough, but you can see where I’m trying to go with it. I don’t want it to immediately look like a vector pic. Those hard lines, though … those are what give it away.
