This might be our largest photo collection in the study store to date: Jorge Zam has put together a massive collection of 156 photos that include standing, sitting and floor poses, all of them ideal for gesture drawing and anatomy practice. You can add all of them to your study rotation for $4.49, and I really do encourage you to spend a few dollars to support Jorge for all of his amazing contributions to this community.
In this photoshoot, Jorge's figure is partly covered from the front for some mild modesty, but his glute muscles are still visible.
Here are a few sample images:
But I strongly encourage you to check the study store for more sample photos!
