Beginner need guidance.

Hi, I've recently started figure drawing and i've been trying to improve on it. I'm trying to tackle one thing at a time but doesn't mean I won't be gesture drawing or just drawing for the fun of it once in a while. It just means i'l be more focusing on strengthening one part of the figure drawing.

Please have a look at my face study, i've been following "Proko" on youtube for these studies. I've been trying to get the basic structure of face right and then building up on it with eyes, nose and whatnot.

i like it, it looks nice, there's this one where the guy's smiling , that one looks a little bit off for some reason, im not great at gesture drawing but, what i can say to you is, keep going, you're already better than me n_n
