Bark, Socrates is very recognizable, you can feel his stubbornness. As a critique: the noses do not match, the left one is tilted too high. And the dark spots may be accurate according to the light situation, but ask too much for attention, leading the viewer away from the facial expression. Your penciling is good enough, now it's time to decide where to put emphasis.

Hi bark, Thank you for being open to feedback. At first glance looking at your profile take, the nose is too small. Assuming that these statues follow the rule of thirds I would recommend beginning with a Loomis head and go from there. Have you had the chance to watch the free lessons of Proko's head structure in protrait fundamentals course? I highly recommend it; it's helped me tremendously understand the placement of the features. With the ear it looks too low; one rule of thumb for the ears is that the top is in line with the brow ridge and the earlobe with the bottom of the nose wings. Even if the view angle changes the placement of the ear will deviate but not too much. I have attached some suggested changes. I hope they help. When placing your eyes it might be helpful to do the sunglass concept; it will help you placing your shadows too. The most important thing is taking your time. If you can get the proportions and placement of things correct, the rest will take care of itself. I hope this helps.

Hey bark, First of all, when asking for critique on a drawing done from reference, it would be good to include the reference, or it's not really possible to give good feedback. So, here is what I see from just a structural point of view. First, the head is not symmetrical, which can happen to the face, but yours is beyond what would be normal. Also, your features of the face do not line up with each other or the center if the face. I included a sketch to show you what I mean, I hope it's helpful :)
