Well, if it's just personal taste, that's fine. I was simply stating that whether you're drawing portraits or fetish stuff, if you're dealing with someone professional, it's good experience. Not to mention that although the world seems like a giant place, you'll see that businesses and niches are surprisingly small circles. You could do a cover here or there and have your name spread to the point where maybe you're doing one piece a week for someone, or maybe one piece a month for four different people. Say it's a measly $50 per piece. $200/month would pay most people's car insurance, or maybe car payment, I don't know. If you own a home, right there's about four electric bills+. Whatever. I guess I assume from the pages and pages of threads about art here that a few of you would actually like to make this a part of your livelihood. At that point, your talent becomes a means to an end, and when easy money comes along like that, someone should grab it.
I always wondered what it would be like to be the guy who sits and does layouts for porn catalogs. With a matter of fact/been there, seen that attitude, you have to access all these hundreds of photos. Then you have to creatively design pages around people boinking, etc. And when you think it looks pretty good, you have to take it to your boss and see what they think. And if it's a go, you call a printer and go over and stand in front of everyone during a press check and mark it up with a grease pencil and make comments like "Their skin is to red here and there's too much blue in the semen on the facial on page 23". If you're the printer, you could have church calendars on the press in the morning and something like that in the afternoon. And I've never walked into a printer where they showcase porn catalogs on the walls. They do it, but they don't talk about it. It's just money to them.
Trust me, I'm not trying to talk anyone into anything. Do what your comfortable with. But your first big break may not come when you expect it to and you may have opportunities in the mean time for money or learning. That's all. I wouldn't sweat the anonymity, though. $600 is the cutoff or reporting it. If someone pays you less than $600 per year, that's a non issue. If they pay more than that, you get a 1099 form from them stating what you made. It's not itemized that you did fetish art. They could have paid you $800 to cut the grass that year. Nobody on the planet would know the difference.
And with that, I rest my case.
