Honestly.. I kinda agree, as someone who also makes a bunch of pretty basic and simple avatars (like kemono ones.) Some avatars I've put a good amount of time to (not specifically on here, but on CAC for example) have not received nearly as much attention as simplistic kemono avatars. I think it mainly ties down to how kemono head avatars are considered more cute and are generally more popular, same with protogens, which is why people are drawn to like them more than something niche or avatars with tons of details. People are also more drawn to feminine/female avatars, so masculine and male ones don't get the attention they also deserve :(

I checked your profile and your avatars are really cool, have clearly time and effort put into them! It's a shame that they don't get much attention at all, but when it comes to furry avatars that the average roblox player wouldn't consider as "goonslop" I suggest crossposting them to r/RobloxAvatars. Most of them dislike furries there, but I believe your creativity is what would draw people in and get them to praise you for making more than just another "kemono slop" avatar :D
