Towards the end of his life Pimenov continued to carry out large commissions, his works adorned the Alexandrinsky Theatre and the Imperial Public Library. While working on compositions for Vasily Stasov's Narva Triumphal Arch in the early 1830s, he came into conflict with Emperor Nicholas I, supposedly over Pimenov's portraits of Nicholas and his wife Alexandra Feodorovna. Nicholas criticised Pimenov's characters for the Narva Arch and he was forced to resign from the Academy in 1830. He was able to complete several of his commissions before his death in 1833.
