Select the frame layer. It can be helpful to set the opacity of the frame layer to 50%-60% or so to make it easier to see exactly where to edit the edges of the frame as it crosses in front of the subject of your photo. Zoom in if necessary.
Using the eraser tool, simply erase the part of the frame that is cutting in front of your subject. Since the frame is the only thing on this layer you don't have to worry about staying within the lines. You won't be damaging the underlying layers when you erase the frame.
Reset the opacity of the layer back to 100% when you're done.
