In which I take a crack at 5e Hengeyokai

Okay, I haven't done the 5e-style flavor text yet, but I probably will at some point, I just wanted to knock out a draft of this and get the mechanics ready before I did any of that stuff. But the plan is to make a nice pretty PDF and I'll have the fluff ready then.

Hengeyokai Traits

Ability Score Increase: The ability score that is highest in your species increases by 2 in your humanoid and hybrid forms. Treat the intelligence score of your species as if it were 10 higher than it actually is for the purposes of this trait. In the event that two or more scores are tied for highest, you may choose which one to increase.
Age: Hengeyokai mature at about the same rate as humans, reaching adulthood in their late teens. They live slightly longer than do humans, usually around 100 years.
Alignment: Free-spirited, even capricious, and playful, hengeyokai tend to be of chaotic alignment.
Size: In their humanoid or hybrid form Hengeyokai are about the size of humans. In their animal form, Hengeyokai are the normal size for an animal of their species.
Speed: In humanoid and hybrid form, your base walking speed is 30 feet. In animal form you have whatever speed is appropriate to your species.
Shapechanging: Hengeyokai can change their shape among three possible forms. Your natural form is that of a beast of CR 0, but as an action you may assume an anthropomorphic "hybrid" form or a humanoid form that resembles a human with features reminiscent of its animal form. Your human features are always the same unique individual, as are your features in both hybrid and animal forms. You may change shape a number of times per day equal to your level. While you are transformed, the following rules apply:

• While in animal form, your game statistics are replaced by the statistics of the beast, but you retain your alignment, personality, and Intelligence, Wisdom, and Charisma scores. You also retain ali of your skill and saving throw proficiencies, in addition to gaining those of the creature. If the creature has the same proficiency as you and the bonus in its stat block is higher than yours, use the creature's bonus instead of yours. If the creature has any legendary or lair actions, you can't use them.
• In hybrid form, you have darkvision if your animal form would. If your animal form has the Amphibious, Keen Hearing, Keen Smell, Keen Sight, or Water Breathing traits, your hybrid form does as well.
• When you transform, you retain your own hit points and Hit Dice.
• While in your animal form you can't cast spells, and your ability to speak or take any action that requires hands is limited to the capabilities of your beast form. You may, however, communicate with animals of your species (or closely related ones as defined by the DM.) Transforming doesn't break your concentration on a spell you've already cast, however, or prevent you from taking actions that are part of a spell, such as call Lightning, that you've already cast. While in your hybrid form, you may speak normally and cast spells, but you retain the ability to communicate with animals.
• You retain the benefit of any features from your class or other sources and can use them if the new form is physically capable of doing so.
• You choose whether your equipment falls to the ground in your space, merges into your new form, or is worn by it. Worn equipment functions as normal, but the DM decides whether it is practical for the new form to wear a piece of equipment, based on the creature's shape and size. Your equipment doesn't change size or shape to match the new form, and any equipment that the new form can't wear must either fall to the ground or merge with it. Equipment that merges with the form has no effect until you leave the form.

Languages: You can speak, read, and write Common and Sylvan. Additionally, when in hybrid or animal form, you may communicate with animals of your species (or closely related species as defined by the DM.)
