How'd you get so good at drawing robots. Like they look like real robots and not just jointed people shapes with furry heads or whatever the hell. What did you study?
Mostly just studied other good robot designs, both in real life and fiction, and tried putting in some of their details into my own designs. Big thing to making good robot designs is striking a balance of both style and function, with very readable silhouettes that are distinct from what an organic character would have.
If you look at Atlas and P-Body from Portal 2's co-op mode, for example, you see that drawing them realistically is kind of a nightmare, but their outlines and body parts are extremely easy to simplify as they're constructed with shapes that are easy to read and reinterpret. Then consider that most of their actual body parts still make sense when you think of how they work together. You see what looks like hydraulics in their shoulders and legs, and when they walk you can see these pistons push and pull to make everything happen in just the right ways. It doesn't matter if a seasoned engineer might see some inconsistencies; for the average viewer, it's believable. The viewer is convinced this isn't just Mike Wazowski in a robot costume.
Modern Metal Sonic's hyper-detailed 3D renders work pretty similarly, where you can simplify him to how he looks as Classic Metal, or go bananas and make all the joints and parts detailed. Either way, you can see that all of his joints are designed with degrees of freedom accounted for, hence "function", and yet you can tell him apart from other robot-sonic designs and remember him for his iconic look, hence "style". A recognizable, sharp robot, through and through. When designing a robot, you have to keep these kinds of ideas in mind.
