I wish your head designs were cooler. Try lowering the eyes and rounding the heads more. I get that they're robots, but the box heads don't match the bodies. Still, it's a great picture.
Well, that's pretty subjective, I guess - and it's absolutely ok not to like it I'm not sure if I agree about the mismatch, but such feedback is always welcome and I will think about it. Thanks for the feedback!
Don't get me wrong I really do like the image, the style is perfect. I just think that a blocky body goes to a blocky head. But that's just me, if you like it, it's fine. However, I do feel the need to inform a fellow artist of my recommendations, as helpful advice, not an insult.
