I don't know exactly what u'r tying to blend, but if it's the beggining of the hands and the shirt. You can do this, if u have two separate layer, one for the hands and the other layer for the 2D drawing go to; layer-Add layermask-Reveal all. You should have a layer mask now. Make sure u'r background and foreground color are at white and black. Now make a selections that u want to be blended in such as from the wrist of the hand to part of the shirt etc, it doesn't have to be perfect selection. Now use the gradient across your selection, and it should blend it in very nice. You can do it separetly for each hand. If u want to adjust the blending go to the options for the gradient, where the navigator bar is, and adjust the level of the gradient. This blending mode using layer masks works as it takes what ever is white as the part with the highest opacity, and as it get darker it decreases the opacity, and eventually black will be completely transparent. That is why using the gradient u get an even blend and adjustable however u want it too be. You can also use any painting tool and using black will make it trans parent, and using white will make make it more opaque. Hope that I helped u with your problem. ~HaRoLd~
