My arm bones studies: first ones I have done are pretty weak, but I started to get the general idea of how the bones' attachment and shapes later on.
The proportions are still a little off, but I think it was alright for a first attempt.
It seems like attaching muscles to these will be quite the feat!

Here's my assignment for the arm bones lesson. This one was definitely a challenge for me, any feedback/critique is always welcome. :)

Went back to studying the bones firstly with the arms

These were really tricky , I had to copy Stan for a good part to even visualize the form and relation between the ulna and radius . I did one more ( others are coming ) to help me figure out these bones !
( I already see that I flatened the left Radius on my last attempt )

Very good man!
Just one note, in the third trace on the lady's left forearm the beginning of the radius is on the wrong side :)

Second attempt at Arm bone studies after seeing Stan's critiques and getting some community feedback on my previous ones.
Still had some challenges with the shape of the ulna in some of these
All critiques are welcome

Hello everyone, does anyone has an idea on how are the radius and ulna on his arms. I have some difficulty to visualize them... Thanks a lot

Try putting down where the scapula and humerus are. You know the ulna connects with the humerus and you know the radius connects with the wrist. Also, the forearms are pronated so you know the radius has rotated to cross the ulna. You can see the Afro ion and the epicondyles so crack open an anatomy book with a similar pose or you could use the Skelly app and reproduce the pose to understand it. That’s how I would attack the problem, anyways

Hi @Jason Winter, great job! The overall placement looks good, and you've managed to get the pronation right!
I'll do my best to help you further:
- I think that you are making the radius and ulna too thin at their thin parts
- In drawing #3 I think you got the curve of the ulna wrong. In an anatomical position, it curves away from the body near the humerus, and towards the body near the carpals
- In drawing #5 (handstanding) I would refer back to the 3D-model to get the form of the olecranon right. I think you're making it too wide
I hope this was helpful :) Keep up the good work!

You can find the assignment images under the How to Draw Arm Bones video in the Downloads tab, it should be called Arm Bones Assignment Images.

It's almost there.
You did find the land marks and the shapes of the bones are starting to show some tridimensionality. However you're pointing the bones in the wrong direction. You got the position of the medial epicondyle right but the cylinder at the elbow is wrong. The lateral should be higher the cylinder should be more inclined, yours is too horizontal. The angle of the ulna should accompany that.
There's also a little space between the ulna and the radius, in your drawing it looks that they are glued together.The angle of the ulna in the wrist should be more horizontal (Try do this pose yourself in front of a mirror and pay attention at the position of your hand and how much your wrist rotates).
This is a personal impression, but I think the ulna is too big, Is almost poking through the palm of the hand.
This is a very difficult pose. You can't see the lateral epicondyle , the end of the ulna is hidden and on top of that the arm is foreshortened. So don't get discouraged and try again.
Best regards

Critique and Feedback are very welcome.
I tried to do them first and corrected them after seeing Stans example.

Hi @Nanna Skytte ! =)
I don’t have enough experience yet to be of any help, but I think it’s super cool that you did your work first, and then did your own corrections after watching the crit video, posting both versions here.
