My 1st tutorial =)
From This: 
to this:
Made in Photoshop CS2
Step1 Sharpen your base once.
Step2 Duplicate the base once. Set this layer to Screen, opacity 60%. Go to Image --> Adjustments --> Hue/Saturation and set Hue +36. Merge Layers. This will be our new base.
Step3 Add a new layer and fill with #04062d then set to Exclusion, 100% opacity.
Step4 Add another layer and fill with #c372e9 then set to Pin Light, 40% opacity.
Step5 Duplicate the base and drag it to the top, set it to Soft Light 100%
And your done!
