Perhaps the personality type you were trying to describe is cynical? Forgive me, I often try to simplify things. You appear to be a bluntly honest person as well, based on your description.
As for a design being influenced by yourself, I think that happens to a lot of us. I personally always drew my characters with a short hairstyle and didn't realize it until a few years later. I also found that I actually have a hard time drawing, or getting into drawing long hair because of this. But that's because I subconsciously apply many of my own physical traits. personality traits are harder to notice- and appear to be your dominant side for character design.
That couple is adorable though. c:
Anyways, nice to meet you! Hopefully you'll get to know folks around here well.
