Detailed black and white illustration of a stylized creature skeleton forming a decorative frame with fin-like spikes on a black background.

I want to design a painting that I'm going to do on a frame, a picture frame, which is like an A4 shape, so one long side and one short side in a rectangle. It's black. I've attached triangle pieces that stick out each corner, like fins, and then on the long side, there's a triangle piece in each center of the long side. The whole thing's painted in black, and I want to paint a skeleton silhouette on in white, but I want it to be formatted to fit the frame's design, like bones that would naturally go into those shapes, big long bones, and then maybe thin bones that go into the triangle pieces. Can you understand what I'm asking? The bones should be rendered almost like the frame itself was the animal, and the bones inside are rendered onto the shape of the frame. The triangles are about equilateral, sticking out, and they're about 3 inches. The frame width is about 1 inch. They should be like long bones going down the long pieces, and when it hits each triangle part, render like a fin bone structure or something that fits in it. See more
