Old indeed. Picture could have used a bit of a wider crop - the way it butts against the left side and is maybe even cut off a bit on the top makes it feel cramped. Sepia toning is a good idea but this seems a tad on the pinky side.
There are a few things that might make this better. First, the frame of the picture is too tight. There are parts of the gun that are almost touching the edge of the picture. The border actually draws your attention to this since it actually touches parts of the gun like the barrel and tire. Second, the color is a little too pink for a sepia effect. More yellow would help this a lot. Third, the Depth of Field is too deep. Opening your aperture more or using the portrait setting would help blur the background and keep your attention on the subject.
