I've been seeing this floating around here and there in multiple art communities: the idea that using references for your art means you're somehow not a good artist or that it doesn't make it entirely "your drawing". I can't speak for everyone else but i personally feel that this is a load of bologna.
There's absolutely no shame in using a reference for something, heck for that matter i encourage it, you would be amazed at the difference that it can make for your art! Even the pros did it, heck, look at what Van Gogh did to his ear just to get a proper anatomy reference. x)
That being said, be sure that you are referencing from sources that you can absolutely make sure that they allow it, so that you avoid any possible copyright issues because that just ain't fun! So with that said i'll go ahead and drop in a few sources that i regularly use that have a "free to use" type of policy for their images. ^^
Pexels , Pixabay, unsplash , Reshot , And don't forget that there's also a stash of pictures that CS itself has provided for us to reference from. ^^
Of course, remembering to link back to what ever you referenced from. c:
Annnnnyway just wanted to get these thoughts out there.
