>>9329810I really like that Klaw pose but Tiger Shark could use a bit of work.
When squatting like that, the toes shouldn't be pointed in opposite directions, it looks unnatural and IRL would be quite unbalanced (try it yourself and see). It's a problem with all of your squatting poses and why people have commented that it looks like they're taking a shit. Try something more like picrel instead, where the legs are bent at different angles and the feet are pointed closer to the same general direction.
Also, technically Tiger Shark's fin should be attached to his back as well as his head, try positioning it on the other size of his neck as I've done. But that's just me being very nitpicky =)
Again, really good pose on Klaw.
