Welcome to the forum. Glad you decided to stop lurking and start posting. I hope you'll take time to listen and comment on tracks others have posted.
Working man: I agree with the previous post--brash mids, too little bass, not much dynamic range. You may have overdone the compression or limiting. I thought I heard clipping going on. The song, arrangement, performance, and especially vocals are really good. It's kind of odd to hear the dobro on the left so in-your-face while the vocal is a bit more wet and in the background. Maybe this was a conscious decision. My preference would be for a drier vocal sound.
Seventeen: Very similar comments, actually. Good song, excellent guitar playing. Way too much compression on the mix. Definitely this one is clipping. Again, your guitars are fighting with the vocals. I'd prefer to hear the vocals up front and drier. The bass sounded fine in the beginning, but as soon the full instrumentation comes in, it gets pushed to the back. I think the compression is taking all its punch.
Good to see another contributor on the forum working in a country-inflected style. I've done one lately, though it is not my usual style. FoulPhil has several tracks up in the same vein.
