Well done, although since you can see through the cocoon (or whatever you wanna call it), I might expect to see (barely) some of the other outer side (the decoration), so you create more the illusion that the foetus/baby is inside of it. Also, there is some light from below according to what I see on the cocoon so you may want to lit the foetus there a bit too. Good luck!

Thanks well spotted! I actually began fixing these very things last night but haven't had time to update it yet...I like how you think!

good idea
