Hi Mauro,
The parts where the Texture doesn’t ‘match up’ are where you placed your Seams.
That is why you often want to use as few Seams as possible and place them where they won’t be seen, or at least not too noticeable..
But it also depends on the Texture you are going to use, how visible those Seams will be; if you are going to paint the model in the 3D Viewport, you can paint over the Seams, so they won’t be seen.
There are also Textures, that can benefit from blurring out Seams.
