Started out as just a sketch of an eye, but added a nose then another eye, mouth then a head, a neck. I've always wanted to do a pic of Lady Heromorph so sketched her mask. Once she had the mask I toyed with the idea of a Teen Heromorph, side kick to Lady Heromorph, hence the schoolgirly outfit, but she doesn't look like a teen, so now she's Lady Heromorph either in disguise or being kinky
You've come a long way bud. I see a lot of confidence in this image. Nice work on the shirt too. As for the head, it is proportional, the eyes are what are too big, but that seems to be what you were going for.
