How's that look?
Here is what I did.
Made a selection with the marquee tool.
Stroke> White > 3px
Duplicate this layer once.
Add a drop shadow to both layers.
Set top layer to overlay, leave bottom layer at normal.
Now just change the Fill (not opacity, but the box below it that says fill) on both layers til it looks right. Mine were:
Top layer: 100%
Bottom Layer: 20%
Only thing that I don't like is I should have feathere'd it just a tad bit.
