Hi guys, this being my first post if im being silly and asking obvious questions please humour me. I need some help making a mould for this wing. I was thinking a split mould as some parts of the wing tuck under and would be impossible to release. Any advice would be appreciated. Thanks guys

Ok thanks for that advice, I was thinking as you can see in the 2nd and 3rd pics (I think) there is a lip that  kind of folds in on the wing. I was thinking if I was to make the mould from there it would get stuck. Maybe I'm over thinking but just want to be sure before I start. As for inner skin, I was assuming its just 1 skin as there is no inner parts too it.
