Alex and Nathan Body Studies

I am currently doing body studies of my ocs Alexander Thornwall and Nathaniel Regalia in light novel story that untitled at the the moment to hone on my art style/skills in order to improve anatomy,etc I will be doing a lot of these for now.  The two are rivals in the story. Both Lorin and Priscilla will get their chance to be drawn as well.  I chose to do the same pose for both as they have different body types. I felt that it would help being to learn how to draw one pose in two different body types as opposed to one. This will be done for all of them. Alexander has a much more buffer body than Nathaniel and this is how I always imagine him. But with my current skills the way I drew him just like many other of my ocs tend to fluctuate. Nathaniel has a much leaner body than Alexander though he still carries muscles. I will upload his character sheet soon just need to color it. Stock of pose use comes from  vishstudio
