Didn't realize you had to mail order ingredients. Your beer will turnout just fine as long as you followed the proper procedures. Never had Mirror Pond, but I looked it up and here's the description
Pale
Alc. 5% | IBUs 40
170 Calories, 12 oz serving
This is base camp, where any craft brew exploration begins. A distinct hop nose and hop-forward flavor make Mirror Pond the quintessential Pale Ale. It is aromatically complex, multi-layered, and unmistakably “right.”
Malt: Pale, NW Pale, Crystal, Carapils
Hops: Cascade
The Mirror Pond is probably a little more complex based on the malt profile and the Cascade may stand out a little more, but you may notice some similarities between the two. Speaking of a whole lot of days, I would have recommended you leave your beer in the fermenter a minimum of 14 days anyway. It's not too late to order your ingredients for the next batch and request an extra ounce of Cascade for dry hopping this one.
Based on the description and IBUs of Mirror Pond, I guessing a clone might look something like 1 ounce at 60 min, 1 ounce at 30 min, 1 ounce at 10 min and two ounces at flameout with another ounce for dry hopping
