I steeped grains for 60 hours. That was way too long! There is a strong astringent flavor from tannin's. Reduce steep time or do a proper mash.
Based on boiling 3.00 gallonsliters at NaN for 60 minutes, this will decrease your wort by 0.00 gallonsliters, bringing your after boil OG to NaN. You wanted an OG of 1.054. It looks like it will be over.
