Here's some design suggestion was hoping for some feedback, or ideas for different designs.

Got some options to consider

1) Twilight only has one bimbo form (from lv 6-10)

2) She has the same design but it keeps sluttyfying for each level (like stops wearing bra, even more make-up etc, still growing curves)

3) As above but with hair and clothing changes.

4) This is more of an S-link idea. If the player keeps her intelligent up, she'll keep have  one the the bottom two hair styles (Normal, or twintails) but if she loses Int she goes with the top hair designs (Twin or pigtails)

I'm leaning hardest for option 3, but her clothing and body changing together over the bimbo levels. So like once her breasts become large enough to render her school jacket useless to cover up anything she'll go without, or her skirt becomes short enough so she can show off the full length of her stockings so she starts wearing them longer. As for her hair or accessories, I'm pretty neutral on those, although I do like the look of the huge top-right ponytail.

So Here's a concept for the 3rd option,  on how it could look on Twilight's progression.

And here's a concept for the 4th option just so show what's possible. While this may be more convoluted, but up for anything. This here is just for going to show what's possible. Now that the main drawing is done, it would take maybe a day or two to make all the needed edits. 

oh and have the current sprites as placeholder here https://ufile.io/sqap5
