Both of these photos are almost straight and almost centered/aligned, but not quite. By getting close to straight, or centered, or almost completely in frame, you give the impression that you're trying to get it straight, or centered, or in-frame and failed. These look like mistakes. My advice is, if you're going to cut off part of the grinder, or get the badge twisted in the frame, go for it. Make it obvious. Cut off a LOT of the grinder, place whatever it is in frame at a radical angle, so we know it's not a mistake. It might be a bad idea, but it's not a mistake.
The first image is too busy, I feel, and could use either more contrast, or be pushed down darker. If it's going to be relatively flat, make it at least dark, I figure. There's no drama in your version, it looks like a mediocre photo of a tool. Try taking a very dark photo of half of it, or a well-exposed photo of half of it, and push the contrast around. You'll see more drama -- you might not like it, but you'll see what I mean.
The second image just doesn't seem that interesting. Maybe if you backed out a little, and made it a photograph of the badge, but with a little more context around it. Maybe not enough to see that it's a grinder, but enough to see that it's something -- leave the something up to the viewer to guess. A little mystery is good, give the viewer a little something to think about.
