Hi! It looks really good so far! super cute character! I wasn't super sure on what he's doing with his hands so I made you two versions. For your original drawing, the palms are facing away from the chest while being close to the body which if you try to do irl, its uncomfortable and awkward. I recommend trying out poses your going to draw by doing them yourself in the mirror! It can catch any strained proportions early on. I would also keep the form in mind, the bicep can be simplified into a cylinder so the clothes would follow that form and wrap around it and add depth to your body. This could be why you find front views a little off. I personally love the cylinder and box exercise in order to understand form.
