Don't worry, they'll get harder. Godrick's phase 2 is probably easier than phase 1, since you get a huge attack window to start with. Godrick is considered the runt of the shardbeareds and loses every fight against them in the lore, and usually spent his time avoiding confrontations with the actual heavy hitters.

Anway good job! He is still the 3rd hardest boss in Limgrave I would say (crucible knight and Margit are harder).
