The shading on the man doesn't match the magazine clipping like the woman's dress did. The color of the mans hand didn't match the rest of his arm and the size of his hand wasn't in proportion with his body. Some of the drawings looked a little sketchy. The outline on some of the drawings could be darker too. Even the background looks scribbled on, the gradient isn't that well done.
I would darken the the background color to make the rest of the drawings stand out. I would have had more detail in the drawings surrounding the magazine clippings too. I would change the size of the mans hand and the color so it would blend in with his arm more. The only drastic thing that needs to be fixed other than the background is the the drawings like the squirrel and tree trunks, they need to be blocked in and not sketchy because it throws off the rest of the picture
