I found what you said about my digital work very helpful. So here are some traditional pieces of mine too. I hope they are clear enough for you. Both critique and redlines if needed would be very much appreciated.
I’m not going to get too detailed cause it’s three pictures so I’m just going to briefly go over the first one with some redlines and then discuss the other two.
So, profiles can be rather difficult. sometimes we have a hard time discerning where facial features are placed and even the shape of the head and how far the nose and lips protrude. You have a good idea of the proportions but I think the head shape is off.
It’s always important to remember that the head is generally round (the skull itself isn’t exactly round but when drawing, round is a better shape to use than an oval for the base of the head). You also want to make a sort of ‘face shield’ to draw the features on top of. Also be careful of making the neck too straight up and down.
Here’s an explanation of how to go about drawing profiles. With practice, eventually you won’t need to do all these steps, but they help you to learn general placement of things.
For the next I would be very careful about drawing poses without a reference.
Most people wouldn’t sit with their legs up that high because it’s not a natural or comfortable way to sit. The elbows would probably also rest on the knees for support.
Something like this would probably be a more natural way to go about it (obviously with the hands as you have them in your original picture).
The last picture is probably the strongest out of the three in terms of proportion and structure. I would say that the hand might be a bit too box-ish but I think that might be due to the need for some creases on the palm and the fingers being up a bit too high.
