During ZZZZZX arrival into ZZZ descended to 12;000 at ZZZZZ.  Prematurely started descending to ZZZZZ1 (11;000) before reaching ZZZZZ2.  ATC deleted speeds; was a little preoccupied checking speed; making sure I did not have a speed deviation.   First flight in almost three months.I need better situational awareness.
ZZZZZX Arrival; After we leveled off at 12;000 feet at ZZZZZ; the FO set next altitude of 11;000 feet for ZZZZZ1 with confirmation. Approach Control notified us of a new ATIS. During our level off at 12;000 feet I copied the new ATIS. I looked up at the PFD and noticed we had vacated 12;000 feet prior to ZZZZZ2; and shortly after crossed ZZZZZ2.[Suggest a] digital ATIS.
Air carrier flight crew reported not making a crossing restriction during arrival.
