I messed up...how bad is it??

Ok so i am gunna make a 5 gallon batch of centennial blonde and the recipe says it need half a pound of crystal malt and my dumb ass ordered 1 and half punds on accident and all the grain is going to be milled and put together in one bag. SO how much will this affect the outcome of the beer? Here is the recipe by BierMuncher:

I think you could call it dirty blonde. The color will be darker, and you will have more malt flavor in the beer than intended by the recipe. Other than that there will not be too much of a difference. RDWHAHB

The good news is that is wasn't crystal 120. It wil be sweeter and if it were mine I would add some more base malt and make it hoppier.

Crystal 10 is just going to leave it a bit sweeter. Should be fine.

thanks everybody :fro:
