This map does run into the usual pit-trap of Italian unification happening with French support, yet Italy not ceding Savoy and Nice to France. Which is an issue, and an ugly-looking one at that too.
Were the French that hot for Savoy and Nice that it outweighs any other consideration they might have for supporting Italian unification, such as support for democracy and national sovereignty, hostility to Austrian tyranny, supporting fellow Latins with the hope of creating a potentially valuable ally, an opportunity to screw with the Habsburgs (always fun for the French), etc? Sure, Napoleon, 'cause grabbing stuff is what Napoleons do, but the average French politician? The average homme dans la rue? Were people seriously getting worked up over and drawing maps including and bemoaning the unfairness of France not owning areas that hadn't been ruled from Paris (aside from the Napoleonic interlude) since, well, never? 
(Of course, I may be utterly ignorant here and there was serious Nice Fever in France at the time. Please point me in the right direction!)
As for it being ugly, you're right: the kingdom of Savoy needs to be bigger.
 Not including the occasional "Lord so-and-so held the city for three years in the 17th century" type interludes.
