I do the tectonic work by hand too , I find Gplates an useless overburden that takes too much time to learn and even more time to use in a proper way...
I'm a full time artist/illustrator. I mostly do freelance character works, DnD, Elder Scrolls, Wow and many others. I did masonry for about a decade before going full time with art. I've been doing some watercolor and acrylic paint works recently to get used to physical mediums again.
