If you are tracing (even for just the anatomy), I think some people will consider it as stealing the pose. No matter how general a pose is, there are still infinitely many angles for the same pose, so it's hard to end up with the exact same one. Just try searching for something like "archer aiming" or "playing violin."
Uhmm...Ang alam ko kasi dapat acknowledge mo pa rin yung source kahit pose lang. Basta siguro acknowledge mo yung reference ok lang Tsaka indicate mo na gusto mong mas mabilis matuto sa structures kaya mo trinace kapag ipost mo Ok na siguro yun. Masyado ka namang strict sa sarili mo hehe
I guess you could compare it to using a base? Though you actually draw it 'yourself', still, I wouldn't.. do it. I think you're better off using actual photo references, and stylize those if you wish to do so, or maybe even take pictures of yourself in said pose (unless you're male wanting to draw females, it's possible but eh)
I would link you this one site that I know of but I can't seem to remember what it's called, but it's like a thing where they put a timer (you get to choose the amount of time) and it basically does a little slideshow kind of thing where you have x time to draw the pose/gesture/body/whatever. Will most likely help you improve. (though this is one of those things I tell other people to do but then I don't do it myself, but srs, it's helpful, lol.)
It helps you quickly sketch out the gesture and I guess flow of the body if you do it the right way, which might help you with that.
