Well, it really depends on where exactly they fought. I know that it's a pain, but I cant (and I doubt anyone can) give a straightforward answer. Not only is it about the exact site, but if the terrain is properly utilised. A commander skilled at forest warfare might be useless on open plains. But the most likely outcome on open plains is the curb-stomping of the English, since the French are superior in terms of cavalry, and if the area is dry and stable, will close the distance with the longbowmen before the English can bring their firepower to bear properly. Of course, light cavalry would be superior to knights in this sense, being faster due to less armour. I'm not an expert on the internal workings of medieval France, or the feudal system in general, but with less nobles dead on the battlefield, France may be more fractured internally, but the English threat will be less, as Henry will only be able to make limited inroads because he won't be a hero, and will have less internal issues. This could have effects that preserve, at least temporarily, Scottish independence, the Lancastrian monarchy might even be overthrown by a noble who claims that Henry's intervention in France is threatening to ruin England. In the worst case scenario for England, France can push the advantage, expel them from France and England descends into Civil War, but I don't think it will realistically that decisive, since there weren't that many English soldiers at the battle. What would be VERY interesting is if Henry was captured and killed, instead of ransomed.
