I do like most of them for what they are, but I do have to agree that the cry should be more or less what the pokemon would sound like. For example, I kinda like Wahrer's version for Revanankh's cry more than Briyella's: while it may be more basic, It'd be what I expect from a pokemon game. I mean, I'm kinda imagining that you're telling me Revanankh is some gen 7 pokemon, and that was it's cry. I personally wouldn't believe Briyella's, especially when compared to Wahrer's. However, I do like a lot of Briyella's cries, namely Cyclohm's.
One big thing personally: Tomohawk's cry is kinda cutesy pootsy. I'd much rather it be a bit agressive. I imagine it being closer-ish to Noivern's cry.
As for the musical sounds, I feel like a little bit is OK, but listen to cloyster. It doesn't sound like trumpets unless you de-distort it in your mind or something. It sounds like, idk, water and bubble sounds (Not really, but the idea is there-- a lot of "pops" of a trumpet, if that makes sense) The cry should give a feel of that pokemon. This is super-hard to explain, but if you listen to like, sylveon's cry, you get a feeling it's a cutesy little thing, rather than like, tyrantrum's cry, which just sounds like the big badass motherfuckin' T-Rex he is. There's more to that, like how big a pokemon is, the lower/possibly louder its cry. Compare a bear roaring to your chiuahua (fuck spelling) barking. Bigger animal, lower/louder cries. And you don't expect a small dog to have a humongous roar either. So like, keep the echos for them ghostlies, give like battle cries to Tomohawk and whatever other fighting types, y'know. For something a bit...odd-bodied like Fidgit, go ahead and get weird with cries, though.
But these are super-legit. Thanks to Briyella and Wahrer, and anybody who makes them!
