Hello there, I would like to give some constructive feedback with the art that you made (Just the first post). Having the green (circuit boards?) just below the ears is to me, extremely distracting, especially on the left as it seems like it's a hue between the arm and head instead of something that is intentional. (Note that I can easily be wrong about that and it was intentional.)
The style is pretty good overall. Seems like you have a passion for it which shows. I hope that my constructive feedback helps, if you want some more please let me know, I would love to help you improve your work even more
