My website is www.PoseMuse.com . There are more pose references like these over there. All of them are free to use for your art. The poses are also compiled into ebooks on Gumroad and paperback on Amazon. If you want to give thanks or just support another artist/author, use my discount code JULY30 and snag a pdf for yourself at http://www.gumroad.com/posemuse 

I hope the free poses in these posts serve you well! JM
