Frogs

I just finished the Intro to Organic Forms and did the Frog Workout. I really struggled with this exercise, but somehow managed to get through it. The next day, I tried drawing a few more frogs just to see if I could do it again on my own. Now I'd really love some feedback, because at the moment I honestly have no idea whether what I'm doing is right or not.

Looking behind shoulder pose

I struggle with trying to do a look that goes from looking behind the characters shoulders, i feel like the arm is very off, maybe the chest but I am worried about how the back looks and if the back muscles make sense

Portrait

So could I do sommething better? Its rather an old drawing I did a decade ago.

And the pitch goes just a little bit wide!

I am somewhat happy with the result of this mannequin. However, I feel that the twisting of the torso to pelvis is not caught. The chest was almost straight on with the photographer but a little of the right side was visible. Adding a center line to the chest, abdomen, and pelvis helped a little but I still feel that something is off.

Figure Study

Hello! I would like some eyes on this study and see what is working and not working (proportions, gesture, value, structure, all the fundamentals). Thanks! I had some trouble sort of visualizing the forms of the figure and setting up a good base for establishing the values on the forms of the figure. I definitely do think everything is simplified in terms of structure, but I am open to any kinds of feedback regarding this study. There is just something about it that I'm not satisfied with...

Defiled King

I'm trying to figure out what might be holding this picture back, I'm fine with the composition but something is just wrong or off that keeps me from getting that feeling of life I get from other concept artist's work.
