After passing a Blender course, I've decided to take a quite simple model from an old game of "O.R.B.", and remodell it taking in account all the texture details.
Well, It took me more than I've expected, but I finally did it. Quite simple shaders as my laptop started to die, but it's ok for my first time :) If some wants the one can try it, I feel it's enough for this model, mb, later, when I will get to the Fencer II.
