He created commissioned sculptures for public installations at Silkeborg Bad [da] sculpture park (Silkeborg)[5] and Elsinore,[6][7] murals, the design selected for the Carlsberg's 2018 Wiibroe Design,[1] and was the inspiration for the Theatrical Organization of Cyprus theatre production In Two Minds.

[8] Until 2019, Krull's studio was at Holckenhus, in the historical corner pavilion loft unit where artists Emil Nolde and Agnes Slott-Møller lived and worked.

[13][14] Carl Krull's artistic style has been described as "seismic" or "seismographic", referring to the sculptural drawing and painting approach that he developed.

[1][17][18] Krull developed the method during a road trip through the United States, drawing continuous lines on a paper tube while acting as a human seismograph, allowing bumps in the road to create irregularities in the contoured lines he was drawing.

[40] During the exhibition Palace Party at Kunsthal Charlottenborg, Krull performed a live, artistic marathon in front of the audience, creating a large-scale drawing over the course of 10 hours.
