After I opened a new file, put the background source, and cut, pasted and masked armadillo's image.
step 3 of 9
Added shadow.
step 4 of 9
Copied and pasted half of metal texture; used warp tool to mould armadillo's shell (in this moment I lowered the layer opacity to see what I was doing better).
step 5 of 9
After I copied and pasted a narrow and long part of the texture (where are the rivets). Also used warp tool to modeling, following the shape of the shell. Aplied lighting effect and burn tool in all pieces.
step 6 of 9
I did the same process 7 times more.
step 7 of 9
Cut and pasted half of the texture again, now for backward part. The process of modeling and lighting is the same.
step 8 of 9
Copied and pasted two small pieces from the texture (if I said cut before, it's copy the correct); merged the layers, used bevel and emboss, and lighting effect.
step 9 of 9
And finally the mask (or helmet); copied and pasted a ideal size from the texture - preferable the part with rivets - cut the eye and ear parts, applied bevel and emboss and lighting effects, and some burn tool. Burn tool was used in all pieces, specially on the middle part, to show it flatless.
