yessssss. Layers are VERY important. You ever use photoshop? Basically it's one layer for the human face, one layer for the asari, and then you just play until they look like one face lol. If you ever wanted, for like $10.00 or something I could make one for you hahah.
Oh gawed. My earlier comment? ignore it. XD. Shows how much I pay attention, I thought you were commenting on a completely different pic. OKAY. BACK TO SQUARE ONE.
LAYERS? Not really. I rarely had more than 1 layer going on in this pic. I pretty much just made a scribbly mess and then wittled it down with really high opacity brushes until it started to take shape.
(I thought you were commenting on my asari pic for some reason...the photomanip...where layers are extremely important to get the right effect. XD. DERRRP I feel dumb now)
