First of all, very nice work. It has a Katsuya Terada vibe in it. Great piece ! You mention Perspective in your question and so that's where I will put the emphasize. We can improve that aspect by adding extra care to the shapes (and when I say extra, I mean it, your work is already great) I notice that the cylinder under your character's face is an inbetween Over/Under the horizon line. I will suggest you to make a decision in here since it can confuse your drawing if the directions are unclear/misleading. Since we look at you character from under (Low-Angle shot), I will apply low-angle for the rest of the subject. You will no longer have an inbetween for the second part of the neck, rather an under view of that part too. The face's features are nicely done, I would suggest to touch a bit the nose so it follows more the curve (and perspective) of the face and lower a bit the eye on the left. (the right eye of your character, I redraw-over) I would rework a bit the mechanical part over your character's head. We should see a little more of the front part. Personal note; I would also have more volume to the hair. (hatched area reflect the bottom part f the hair) I hope this feedback is helping. Let me know if you need more precision. I which you a good work. Shadlow
