I don't know how unpopular this is, but I think the trophy wall concept got popular exclusively because it means artists have to draw less and less of the victim. Just their head and their feet, shit's easy as can be. People used to accuse stocks pictures of being this, but the trophy wall I think is impossible to defend as not being just the reduction of work on the artist. There's not even any posing and almost no way to make it specifically unique, you can bang that shit out one two three. I think it's a fun concept in moderation because I like the way it objectifies the victim, turning them into a literal trophy, but as someone who likes interesting character designs and unique outfits, it really hinders a lot of the enjoyment for me.
Related to the last point, stripping characters nude for tickling art will always annoy me. I also think it's an excuse to not draw a difficult outfit but it makes every single lee look the same and reduces them down to just a hairstyle and skin tone. Princess Peach has a pretty tough dress to draw so a lot of people just strip her down to her bra and panties or naked, but that fancy dress is part of why I want to see her tickled! It's that added sense of elegance and class that appeals to me seeing her get tortured into submission! Stripping her down just makes her look like any other blonde bitch. This might also be specific to me because I genuinely don't like seeing pussies in my fetish content, they just actively don't appeal to me in any way. For some reason I get no satisfaction out of seeing a pussy tickled like I do seeing a cock tickled. Boobs getting tickled is pretty good, though, I can get into a shirtless woman getting tickled.
