I think the Valk matchup might be just slightly harder than you listed, but I wouldn't say as bad as Litchi or anything. I feel that Valk has a superior poke game, and his maneuverability makes it extremely difficult to lock him down. Not to mention his insane wolf mixup that is incredibly hard for anyone to deal with, and his damage is very good. I've been blown up for throwing out a 214A/B at a seemingly safe range from his wolf airdash shenanigans into a big combo. I feel that I'm adapting to the matchup a bit better though, so I'll have to see if even more matchup experience changes my opinion on Valk, but there's no doubt that the matchup is in Valk's favor imo.
EDIT- I should note that I was playing one of the top players in the MI scene for this matchup, and I came from Valk in CS1/2, so I do have some base knowledge into how the character works.
