Narrative:

Flight was from ZZZ-ZZZ1 IFR clearance in VMC albeit some smoke.flight was cleared to 14;000 feet then changed to 13;000 after passing 12;000. Looking directly into the sun through smoky haze I did not get it level at 13;000 and busted. ATC made no comment; perhaps due late change. No traffic in the area and no conflicts. This was the second flight in the airplane in 6 months due to covid shutdown. I attribute this to my fault with a little help from late altitude change and general overall covid-19 rust.
