I can't make a living doing these characters. Or, if that's possible, it's certainly not probable. Not by a long shot.
So what would I like to work on that does seem like it would be more reasonable to make a modicum of moolah on?
Crests. For clubs and groups. I feel like this is an untapped thing. Like, if more folks realized that they could get something like this done, they might. I've even seen more 'official' types doing this based on family lineage and whatnot. I wouldn't try to put on airs like that. I would just assemble cool symbols for things your into. Or if your D&D group has a certain collection of character types and items that might be assembled into a crest in a cool way....
I really would like to work on labels for a distillery. Heck - those crests mentioned above would work for this. Something fantasy or viking theme, obviously would be ideal, but really, as long as they understand my style and aren't looking for an anime artist (because we're all the same, you know), I'm game.
Oh, who am I kidding? I would absolutely draw anime if that's what they really wanted.
Beer labels would work too.
I'd like to do some more tattoo designs (see some previous work here). That's unlikely though because most tattoo artists will do the design for free (or nearly so) and if you've done your homework on the artist in question - you know - because they're going to put their art into your flesh forever - you presumably already like their style.
What else?
Pet portraits or portraits of real people. Especially if it's a mashup of fantasy and reality. "My buddy as a barbarian." That kinda stuff. I'm admittedly not amazing at likenesses, but I can make it work, and honestly, it's an area I could use more work in to get better.
I've started doing tee shirt designs, but I'm really an amature. I've got a buddy who does a lot of graphic design work for cannabis companies and he gave me some great feedback on the existing designs in my merch shop. That said, it also made it very clear how far I have to go before I'm, you know, good.
