Yoo, it's nice to see you branching out your art! I like the color scheme of this lil bot, instead of using a cold gray, the white and purple tones compliment the design. If I had to change anything, it would be to either make the robot more chibi, kinda like Astro Boy or Mega Man, or to go more detailed similar to a transformer or Metal Sonic. This design feels like its in a weird in-between of the two extremes.
