It's a debut puzzle today, so welcome to the fold, Mr. Yut! And I love your theme: it's a knee-slapper! Kept me on my toes, so to speak!
Yeah, so, the revealer is SHOWSOMELEG, and I needed i. And it is the purest example of why we don't need circles or shaded squares with a well constructed revealer. Hidden in each of the other three long across answers is a body part related to the leg. In each case, it crosses the two words, just the way we like it.
In terms of the answers themselves, I like TROPICALFRUIT ("calf") and RIDGEMONTHIGH ("thigh") just fine. However, BANKLENDING ("ankle") feels like an ad hoc phrase. Certainly, we'd all accept a "bank loan" as a thing (and many of us, I assume, have accepted a bank loan in his or her life), but this other thing sounds more corporate. In any case, it's not terrible, and I can't think of another example that would work ("Crank lemon"? "Thank Lenny"? "Spank lead"?).
Outside of the theme, I liked STREETCRED, and I liked UMATHURMAN getting her complete name in a grid, rather than just her first name as a piece of crosswordese glue. I also enjoyed AMERICAS symmetrically placed opposite from SUMATRAN, appropriately given their relative places on the world map.
I had very little to complain about. Yes, the NW and the SE corner are replete with crosswordese, and to that point, 1A: Places for hosp. scrubs (ORS) gets a D. It was also my first answer. But I liked the grid overall, and the theme was fun. It was perhaps too easy for a Wednesday.
Oh, it's been some time since HOMEEC was "for-girls-only", hasn't it? I took it in the 70s. Just sayin'.
