Hello Pastabrother.
Good job for making an effort at drawing, it's always a first step, and next would be to keep the streak going!!
Now, for the artwork you created, firstly I will point out the good things, and that is the strokes of each drawing are clean and confident, that's a good and you have nshiedshy away from trying out the complex pose, so good work.,
Secondly, proportion is a bit off, so I would recommend learning about that, as it will help you grasp complex poses. Next, perspective is also important. The 3/4th view head would be in a perspective, so knowing a bit of that will go a long way...
I am still learning, so if there's anything I pointed out that was a bit harsh, then I apologize!!
Happy Drawing!!
