So I found the coolest app today. I don't Know if I'm late to the party or what. but it's going to help me so much with references. no searching 100s of reference stock images or coming up on the fly with poses that just look a little off, when you are trying to capture that perfect image in your head. it's called "Design Doll" ill put a link at the bottom. their free version is all that's anyone really need. that being said, there is a paid version that gives you a few more features. but personally, the free version is all I need.
Website: Design Doll
Here are some example posses I came up with getting to know the application UI. its pretty user-friendly. I figured it all out without the help of any tutorials. it's a fairly lightweight application haven't had any problem running it on my dinosaur of a computer
Hope this helps some as much as it helps me. Enjoy!
