However professional you believe photos appear to other users, there's always room for improvement. For instance, did you use professional lighting to make your object appear as it should, in the correct lighting conditions? I bet your camera saved your photos as compressed JPGs, which means that they already suffer from noise, however many pixels your camera supports. You need to work with RAW or uncompressed TIF images, if you want professional-level photos.
