Even though Ludibes is an excellent designer, no question about that. He's a very strong minded person, so bare in mind that if you don't agree wit him, this might lead to discussions.
In the end I'm pretty happy with the result, but I'm not happy at all with the way things went. OK, I'm also to blame for that, because in the end words were exchanged and I'm not proud of that.
Bus as a customer I pay for a service and I want to be happy with the result in the end, that's the case for 90%, but since I requested some extra change, because of the fact a second concepts wasn't designed (on my request, because the situation was already getting out of hand) .. I think I was entitled to that.
Bottom line, if you wanne work with Ludibes, make sure to first agree on everything and make clear arrangements so there is no discussion afterwards or during the design process.
