This is a writer's board. Why do you keep showing us drawings?
I think nothing of your characters because one sentence and a sketch is not enough for me to try to form an opinion with.
I also think, on a tangentially-related subject, that needing the validation of others is a bad thing for an artist. It makes criticism sting too much, and that can lead to the artist giving up in dejection--which is not a good thing, because art has value to the artist even in the absence of an audience.
Also, seeking validation from others is a gratification we sometimes pursue instead of creating more art, i.e. it can be a form of procrastination.
When you ask us, "What do you think of my characters?", you should first ask yourself whether you genuinely want feedback or are fishing for compliments. If it's the latter, then avoid asking the question, because we're not here to pat your head, and it's a bad habit to allow your happiness to hinge on the opinions of strangers. (For starters, you can't trust them with your happiness. They won't care about it as much as you do.)
