Welcome to LST!
Unfortunately, there aren't many tattoo artists who frequent this forum anymore.. it's mostly collectors or folks who are new to tattooing, asking if their tattoo is healing correctly. if you want to look back at some past interactions, there are my different threads to be mined with lots of gems within.
I would say that most tattoo artist online interaction is done thru IG. I'm not sure if podcasts and youtube videos count, but if so, we can point you the right direction. For instance, Andrew Stortz has a great podcast called "Books Closed" that often discusses "new information about what kinds of topics tattoo artists are interested in and if there are other subgroups." The latest episode is pretty hilarious, discussing tattooing as a performance art and highlighting this artist who does some cuhhhraaaayyzee shit like tattooing while playing the cello.
There are definitely different subgroups based on all the various styles and people of the world, in general. Not sure how much you already know, but a few high level styles include: traditional, new school, neo-trad, black and gray, black work, tribal, geometric, japanese, color realism, biomechanical, and many many more!
Anyways.... I hope this is a good start and I'm looking forward to seeing pics of your new tattoo.
