Hello Vik Thor. I am currently and continually working on my anatomy as well! I have to say they are pretty good studies. My few crits are though, on the first pic, my eye was quickly drawn to the figures left arm, I am thinking its either too skinny or too small in general. With the second figure I noticed his head was too big for his body. Fix those and greatness will be achieved. . Great work though!
It's a good start, anatomy takes a long time to learn. I've found much benefit from good resources, such as "Atlas of Human Anatomy for the Artist" by Stephen Rogers Peck. Another thing to study alongside anatomy is just the basic shapes of the body. Check out all of George Bridgman's books.
Keep up the hard work!
