Pinup Selfie Girl, (slightly nsfw) (Patreon)

I figure this is as good a point to mention using reference. One thing, I think it's important and it can be critical to understanding the acting of the characters that you're drawing. Even a simple pinup like this, a person acting it out can often bring to the table things you didn't realize were important parts of the image.

That said, I added the link here since in this instance I was clearly just drawing from a specific photo with very little deviation. I didn't really ask for permission to do so, neither do I have to. I don't even know where the picture is from, it was just a picture that showed up on my dash and I thought, hey I'd like to practice that particular bend

But to me it can be a little odd. You can never be totally sure about the sources of the pictures. Considering the clothing chosen, in this instance it's fair to assume this was meant to be appreciated by the public. For the record, here's the reference link in a clickable form. The original poster didn't provide an exact source

Sourcing your images can be a really big headache for an artist. People are often pulling material for collages to some degree or another. They can take a photo of a gearbox and use that as texture for their important city scape, and dozens of other examples in just one picture. And most of the time the work is so trans formative, no one notices. But sometimes it edges pretty close and people start complaining.

It's almost always fair use but it's something you can be thinking about when you're utilizing other people's work whether that's photography, fashion, acting, etc.
