hello friend your drawing is great, i bellive by just practicing you can achieve great success, but if i could give you a few advise it would be 1-try to first draw the model pose in vid stan draws, your self ,then try to draw it again following stan step by step, then do small criticization on your drawing and then draw pose again in 2 mints if you dont like stan s gesture you can search for people that you like and study them as well 2-dont do that always to try to put 70-90% 0f your time just drawing. lastly you can start to change the gesture style ,you draw after 1000hours of learning anatomy and character design and ... so dont be so cautious about if its copying other people or that you want to be original later on, you will find you tempo and style for now just try to study.
