Hi Pilou,
re:
> Yes it's for that i try to make only quads! :)
All quads is one of the things you need to make a good sub-d object but it isn't the only thing.
The quads you have generated there are too small, each little quad will have a very localized effect on the subdivided mesh so it will be easy for there to be ripples and bumps in the shape. With larger quads a larger amount of the model's shape is impacted by each quad and it becomes less likely to have little bumps in the shape.
When bumps are stretched out over a large space they become much less noticeable.
It's kind of like this, here's a curve with a lot of control points, and one with only a small amount:
If I move the points around by the same distances on each, the sparse one still retains a smooth looking shape while the dense one becomes much bumpier:
Basically there is much more opportunity for generating lumpy/bumpy shapes if you have a lot of control points.
So that's again an example of something to avoid doing.

Yes, that's kind of interesting that it comes from only a photo but the result is way too poor quality to actually be used.
