Well, after try to submit a former version of this wall, now I think this one it´s more beauty and elaborated than the other. Winry looks very nice in this art, and needs light and sweet, therefore I´ve used a lot of layers and colour efects, and I´ve edited both images (winry and the pic in the bg, the elric brothers, from another art). In addition, I ´ve added some like texture in certain zones, but probably this layer isn´t noticed.

I take a whole day to remake this wall by the beggining. And I´ve used Photoshop 7.0 to work. My signature (my name and website) is down left in the wall.

Edit: now I´ve repaired some "wrong" areas.But still... I can´t delete that "blurred" problem you reported in comments O.o I´ve cleared the scan, whitch has titanic dimensions for me. But blur problem still remains.
