I am someone who sells art commissions and this piece of software made my job easier. Before I got it, I resorted to making repeated poses (AKA same pose syndrome) and there are days where my anatomy skills would go on vacation without me. Not to mention that when my customer wants a new pose, it can take a few tries before I get it right.
This software reduces the stress and brainpower required to get the job done right in a timely manner. Just pose the model, take a picture, and let the customer see it. If they wanted the pose to change, all I had to do was rotate a joint or two and it's right. Even extreme changes are done rather quickly.
My biggest complaint is the control of most joints. Of course I do appreciate the drag and move controls at times plus the ability to make the pose symetrical and mirrored, but I am someone who likes to have things be refined. This is where I really wish there were rotation controls and the ability to pick the bones like in Blender and Source Filmmaker. I do understand that this was originally a phone and tablet app, but they should have been made for this port. Another complaint is having no free posability with the fingers. Again this would be possible with the features I already mentioned. The last one is having no restrictions on most of the joints. That means you can have an arm clip through the chest, a foot next to the head, and more unrealistic poses that will happen a lot from the controls. I shall say this one more time: Rotation controls and bone selection are key.
Overall, it's a great software for artists and even for those who order a lot of art commissions for it's flexibility and speed. It would be better with refined features, but I say it's a good investment to make.
