Looking for constructive criticism on these two

Hey all,

I took these at work this morning (I work in a factory) did some editing and was curious to see what your thoughts are. The first one built the contrast up a bunch and added some noise to it for a more rugged feel, and added a little vignette. The second, I also built up the contrast and used un-sharp mask (maybe a little heavy on the unsharp mask, idk.) Let me know what you think. Thanks in advance!
