Hi, I will say that your rendering is working out nicely in terms of metalic surface feel. What is an underlying issue, that feels off is the correct construction of elipses and object in general, if you will tackle that, and apply your rendering, the study will look much better. Focus on main sphere and how cylinders will pertrude into it, having that, you can add more cylinders that consist of the wholes, keeping it all in correcr perspective is crucial for belivebelity. I have attached the sketch, if something is unclear let me know. Keep up the good work! | Artwod Feedback
