Portrait on a Wall. 

Mark Beck's "Portrait on a Wall" is a realistic oil painting featuring a quaint house overlooking a vast blue expanse of ocean. The house is rendered in a simplified style, with its white walls contrasting sharply against the red awnings that shade its windows. The artist's attention to detail is evident in the subtle textures of the building and the waves crashing against the shore. This artwork evokes a sense of peace and tranquility, inviting viewers to imagine the life unfolding within the home's walls.
