Hi Chad,
I'm glad so many people have replied already, and I'm about to ditto a couple of points. First of all I think posting what you've got and getting comments, on this forum at least, is a great way to learn. I certainly agree with what David Snyder said above, and also recommend you take David Cuny up on his offers. I too am not a singer, and I had no experience in producing and mastering before coming here - both of which are painfully obvious. I know I've still got a lot of learning to do, but I also know I've learned a lot already from comments made on my prior postings. I pick up a little as I go and apply it to my next ones - and the learning process is fun, even if it is frustrating at times.
I also understand about the time issue. I've had a lot of life happening lately too, and in fact, I haven't had any time for recording/posting/learning since January. I've not even been able to listen to others stuff in a long while. As an example of David Cunys' ability and patients, he helped me with that last song I posted in January. I was experimenting with something completely out of my usual genre, and once again it did not come out well. David asked me to send him my original tracks, which I did. He then remixed and did some adding and subtracting and came up with a much better version, all without me doing any other recording. He also talked me through some of the process and helped explain some things and give suggestions. Fortunately for me, we don't live too far from each other and plan to actually get together in person when my life eventually slows down a bit. Anyway, if you want to hear an example of a not-so-good song and then David's work to make it better, the song I did is at

When I do get some time to listen, I'm looking forward to hearing more of your stuff.
Brad
