I love how well this design captures a turn-of-the-century feel, in iconography, color, and technique - and the characters are fantastic: even the clouds look surprised by the interloper! Radscoolian did a wonderful job conveying the bricklayer's surprise: the twist in his body and his posture, leaning away from his work, brick and tool flying away from him, emphasize the extent to which the fleeing Mario startled the bricklayer.
Wonderful design, Radscoolian! Congratulations on the print. [Nice choice, ApeLad!]
