At least the child in your painting looks naturally shy, given the situation. This in contrast to the cartoons, where the child seems to be taking the lead in seduction. Why ascribe feelings to children which they don't have?
Furthermore, and this is purely my opinion of course - they seem a bit... tacky(?) and I must admit if I had opened this link at work I would have been a bit embarrassed if someone cartoons of young girls like this on my display.
Perhaps at least a more diverse range of sketches would be both more relatable and useful to demonstrate the project.
Regardless, I’m not sure what rules of HN I broke to deserve -5 votes for voicing my reaction to a projects landing page.
These are fictional characters, they can be 500 years old and have 3 penises.
You see, you can't tell the age, you can't tell the gender, because they are not real.
