Off course it's thanx to your great talent that this can be shown. And you bring it very lovely. I like the set, it's very peaceful and classic. The colors give it an extra warm feeling and makes her nakedness less obvious. Not that I don't see her gorgeous body, but it makes it look more natural, more like real art. Others use flashy backgrounds and give me the feeling like :"LOOK, NUDE BABE!".
While your art is much more subtle. That's what I love about it and love how to see these ladies: not just naked bodies, but a woman's artistic/natural beauty!
A lot of guys, myself included, think muscles on women is attractive... as long as they are not too bulky or intimidating. I would venture to guess women think the same way about men, but I don't really know what you think. ;D
muscles on men are nice, but not too much either. if it's something like this [link] I'd rather puke, omg he has bigger boobs than me. gross!! men don't need muscles to be attractive.
well.. a lot of guys... so far most of guys I know think about muscular women the same thing as I do, including my BF. this woman is muscular the way I think it's really beautiful, just not too much. [link]
You can overdo anything. However, 'boobs' like that are not the same as fatty breasts. Anyway, I agree that the image is an example of overdoing the exercises. There are exceptions, of course, for people who exercise to get acting roles in stories about times when muscles were common, like in the Spartan war stories.
As for the woman you linked, that shows good abs but not good arms. Of course, I'm not so picky that I'd complain. Haha.
