I concur with the comments about your chassis, Robo_Sugar, if I may be so bold.
As to the tattoos thing, I think tattoos can be extremely hot. Granted, tattoos can also look terrible, but that's generally just a case of a badly done tattoo or a tattoo of something distasteful, such as a white power unicorn wearing a swastika armband (this is a thing that exists and I've seen it). Personally, I think a woman with a full back tattoo of a wizard fighting a dragon would be one of the hottest things ever, but that's just me
I know it's all a matter of personal taste, but it kind of bothers me to hear guys complain about girls with tattoos, but that's mainly because it's something that some guys get really shockingly mean and nasty about for some reason. There's kind of a sexist undercurrent to it too at times, in that they seem to imply (well, sometimes even state) that it's ok for guys to get tattoos, but that women shouldn't mar their unblemished skin and ruin it for the menfolk. It just kinda gets under my skin sometimes (pun intended).
