The Sketchy Sketchbook of ....Sketchyness!!

hey man! good to see that undertale fanart coming, my brother seems pretty into it these days, i have to find time and start playing it.
About drawing your own hands, i used drawn my own hands for hours a couple years back, maybe.
What i did was either choosing relaxed positions, so it doesnt hurt after a few minutes. (And using a mirror for another perspective) Or limiting my practice to gesture drawings. You know, instead of doing all the measurements,etc... just squint your eyes and try to capture the overall form of the hand, the movement and rithm of the hands position.
Then you can always compare that with the info in some good anatomy book.

Now this is just my opinion but i totally recommend you to stick with those drawings from life, at least i learned much more than from photos. Since you have the subject in real 3d in front you haha.
And a photo will never offer that much information.
