Just curious: Why are you doing a separate render for the rose? Unless you want its opacity different than the girl's, there's no reason to do that (unless I'm missing something) Anyway, the way I understand it, your only trouble is getting her legs behind the tombstone? Here's a couple of easy ways: 1) when she's at the lower opacity, erase the part of her legs that shouldn't show. 2) render the tomstone separately and paste it in after you bring her in. Tip: when your dragging your character (or alpha selection) from one document to another, hold down the SHIFT key. This will force the item into the exact center of the target document. So if the source and target are the same size, you'll get exact positioning of the target over the source. Hope I explained that right.
