I have started posting my illustrations on a Facebook page called Mark Young Illustration. I don’t have a direct link to it, but hopefully you can find it if that is more convenient for you.
I think the difference between a good artist and a great artist is simply this. With work done by a good artist you can enjoy their work and see most of what it is, and the rest you can figure out. “It kinda looks like a building with balconies.”. With work from a great artist, there’s no thinking required, it’s plainly obvious what you are looking at.
At least that’s what I think. But I’m not a great artist. Maybe someday I will be and then I’ll change this opinion.
