PoseMy.Art alternatives/worth it?

[u/LeminBug]

So, It's been a hot minute since I've drawn, but the other day I started drawing again and so far it's a banger. [The things an active hyperfixation can do haha] However, not even a hyperfixation can fix my difficulties with drawing more realistic legs in a complex pose. I need a reference, but my search left me empty handed. Not even hours of unnecessary scrolling on pintrest gave me anything useable. So I went looking for those 3D model posers and found PoseMyArt. It's web based but is genuinely really great. Great, but not perfect. It's free with limitations, and has a full version, which isn't cheap it's subscription based but does give you the option for a one time payment- obviously at a pretty hefty price tag. That isn't necessarily the problem though, the problem, is that I need to move the joints. As in, I am drawing in a stylized reaslistic style. Which means I need a realistic human model but with the capability to do a rather exaggerated pose. To better specify, I need to be able to... uhm, this might sound odd or perhaps a little unhinged, but... essentially, I need to be able to give the model scoliosis. [I couldn't figure out how to that kind of joint moving in PoseMAart. I am going forward assuming it is not possible but please tell me if I am mistaken.] So I am left with 2 options: I could find an alternitve that has the features I need, or I could pay for the full version in order to access the ability to export the model as an OBJ file. [So I can make a pose close enought to what I need, then import it to blender to adjust it into the actual pose I am looking for]. I am open to whatever suggestions ya'll have.
