Would still be useful if you posted update messages here rather than just link to the same unchanged forum post from chat asking for re-review
Reviewed again and it is looking better, although I feel like you're not very well grounded within the Terasology code itself. What you're writing sounds more abstract - you're "creating a character entity" for models, not "Reworking the CharacterComponent and associated engine systems handlers to support new features x y and z"
I would spend some time digging into both the existing addon and the engine bits that loads something like the deer creature into a game world. Identify where you'll attach your new work on top of existing work. Be sure to cover what needs to change from current process / models to your new stuff.
