Daang, that's a difficult pose! Seems like you picked an anatomy challenge as well. So previous art was a hearbreak, this one is a scare, going for emotional roller coaster here?
I think this will be awesome to to to research tentacle structure as well. Go for it. The only thing I'm unsure of is the left arm right now. Not understanding the position at this point.
@chiara.arcidiaco I personally think we should go for an illustration as a final piece. After all, we're practicing translucent skin, which would be difficult to emphasize on, if it is a static character sheet.
