After looking through my folders today, I found this pic I got years ago, and decided I’d finally just upload it at last to share with you all.
 
Basically, this is the ref sheet of sorts of Sam Style, a pony with a unique condition: They start off usually calm, focused and trying to keep their emotions and so forth under control whilst as the stallion at the far left. But the more their emotions flare up (usually arousal, anger, sadness, excitement, ect.) , the more feminine they become. Mainly with their fur and mane/tail turning more and more purple and then pinkish in coloration, their body shifting more feminine in form and their mane and tail growing longer, thicker and larger in size. Until ending up gaining breasts and becoming a full-on mare with a HUGE mane and tail, and only getting bustier and curvier (and with a longer mane and tail) the more it keeps up, until done. And the only way for them to go back to normal is to cut their mane and tail until as short as it is originally. This is why he’s basically stuck as a model pone for a lot of agencies, because he can handle any garbs he needs to wear with a lot of work. And this is also why he is friends with a barber, so he can get tended to when he needs to.
