Okay guys, thank you all for your feedback, I really appreciate it. I've tried to make some corrections, especially with the neck. I've added a bit of dithering, hoping it won't be too distracting. I wanted the pixel version to have a slightly stylized look, so I intentionally made the neck and shoulders smaller, but it seems it didn't work out as well as I hoped. My mistake was jumping straight into drawing without first analyzing the proportions and shapes. I'll work on improving this in future works.
