Well, I’ve tried those wings from 2 different directions ... maybe it’s because I kept so many birds ... have a little trouble believing these things could fly anywhere ... anyhow ... I know many here also use Blender ... and some of this information can certainly translate over to Hexagon as well:

Not all feathers are the same size ... flight ones nearer the end of the wing are longer. If trimmed, flyer cannot gain altitude nor fly at break neck speed [which is the whole idea of trimming a bird’s wings].
As there’s a variance in type of wing [feathers or leather] and direction for fold ... one will need to make some decisions to achieve the desired finish.
When the wing line is decided upon, thickening it will provide some bone mesh. Model it to the basic shape desired. Fill in with “leather” or ‘feathers’ as desired. For the humanoid part ... there are videos for modeling the ear, hands, heads, faces, etc.
I have been working on, and released some other items ... this is still on the burners ... will see what happens in time
