Below is a piece by an amazing illustrator and artist Kayleen West. I just found her blog today and I am so glad that I did! Such an inspiration, and great tips, tutorials and advice for other illustrators and artists.
Once thing I came across today was her post about Artist's/Illustrator's Model Releases. She has a free downloadable template to use here: http://kayleenwest.blogspot.com/2009/09/artistsillustrators-model-release-free.html
This is something I haven't really thought about, as most of the people I've used in images have been friends or family. This brings a whole other point I was not concerned about, but it's always good to cover all bases. Since one of my new years resolutions is to do a lot more oil painting this year, and my main medium is oils, it makes sense to utilize this resource.
Thanks Kayleen for the information and template!
