After some reading around, I decided to make the Emblem from scratch, the shirts with own produced colors, and the players after my own intuition after seeing them on Ciutat de Valencia and their stats in FM 09. I overwrite one of the "PES club" teams.
The shirts look great! The emblem so-so, since I cant put the bat on top, and also beacuse writing in the emblem editor is a hag. (the Levante U.D. name)
The players are going slow but steady forward. I take in use their height, weight, preferred foot, hairtype and color, and leave their faces to random. The most important players I look around for similar faces in the "copy player" option. Or else its impossible for me to make them look similar to real life.
The stats background work is what takes time... But when your a huge fan, what can you do?!
I hope Levante fans can read this and take some suggestions from this. And add whatever they like. I love PES, and the editor option is great.
