Ooo la la, vibrating lingerie. :wub Lillia sounds like my kind of woman lol
As for any critique I can give, this one is hard. I actually can't find anything really wrong with it proportion wise. I think the back leg might be a little longer than the front and larger calf-ankle wise in comparison to the front. the rest of the body looks great for its angle. Oh, perhaps a smaller bellybutton indention line too; that large line makes it seem like she has a few inches in diameter right there :stickout Other than that, I'd say this is your best one out of the 3 in terms of anatomical scale. Excellent job.
For a bf name, why not Alexander (Alex for short)? Or Chad. Or Michael aka Mike. Really there is a lot of male names you could pick. -shrugs-
As for your future pictures, like Phoenixfeathers said, w/e is easier for you. If you're going to do requests AND your own characters/stories, it might be better to make two separate threads. This thread seems to be for requests, so posting non-requests and personal experiments could clutter it up without their own dedicated thread. You can wait to do this until you have more requests filled out, so in the meantime just stay the course right now.
