This bit looks unneeded and should be removed

 

float exposure = key * L / avgL;

 

change it to 

 

float exposure = key  / avgL;

 

I don't see why you need the multiply by pixel luminance

One idea is to convert to a signed distance field. Then find the pixels which are greater in value than its four neighbours ( +/-X. +/-Y)
