Yum. I wondered when I would get to a picture of butter. The light spot on the top right really helps brighten this picture up A 7, mainly I think the lighting and composition could be improved. The lighting with more diffused light, and the composition by eliminating black object on left and rearranging the biscuits. I like the crumbs though.
The butter may be yellow in person, but it came out white in this photo. A change in liighting or a hue adjustment might bring it into line, but this ain't yellow.
