I really enjoy these tunes. I had the opportunity to play a concert with Willie several years ago. Crazy is one of my all time favorite tunes.
Ok mate... Here is my input.
Well done. Excellent musicianship. A very cool retro vibe.
I suggest the following changes:
The reverb. I don't know what reverb it is, but I would try something a bit different. Take a look at any of the convolution reverbs. this material deserves a nice lush reverb.
The lead instruments are mixed perhaps 3db too hot in relationship to the rest of the mix. This also holds true for the lead vocals.
