The Oil Painting is the most serious of the six. There's no crown, no irony, no flourish - just your pet, painted in the way a portrait of a person would be painted. Warm directional studio light from the left, a muted dark ground, loaded brushwork that catches the texture of the canvas underneath. It's the style we recommend to anyone who says they want a real painting, not a stunt. The key distinction from the Royal: no costume. The sitter is rendered as themselves, not dressed for a joke.
It pairs with the rooms that already have something serious on the wall - panelled studies, dining rooms with antique furniture, fireplaces with stone surrounds. It also reads beautifully in a minimal modern interior, where it becomes the single warm object in a cool room. The technique sits closer to Velázquez and Sargent than to Reynolds - less decorative, more honest.
The Oil Painting works on any pet, but it particularly flatters short-haired breeds and cats with strong, simple markings - black labradors, tabbies, sphynx cats, dobermans, pointers. The brushwork has space to breathe across an uncomplicated coat. The file is 4,096×4,096 pixels; printed at A2 on matte paper, the brushwork and canvas texture are both visible from across a room.
