^Yeah. you should never over sharpen
this is The way
I do it =)
First, you duplicate base. Then set that base to Overlay at 100% opcacity.
Then, again, duplicate the layer you duplicated.
Then, make a new layer, and fill it with 1e0d9a. Set it to lighten at 100%
Then, make a new layer, and fill it with f7a420. Then, set it to muplity at 25-30% opacity.
After that, flatten, of combine all layers. Then, go to the filters.
Go to Filter>sharpen>sharpen.
