About six years ago i made a small pixel image, enlarged it quite a bit and applied one or more filters in Photoshop to make it look cool.Now i want to make a similar effect on a different picture, however i am unable to find what i did to achieve this effect.Does anyone have a clue of what it is that i might have done? i have gone through every single filter in CS5 and i am not finding anything that produces the same effect.
Here is the before pixelated picture:

Here is the after picture (added color to eyes manually):

Please Help!
