There are certain skills and rules, required for Song writing, you should know these and incorporate them before you ask others to critique your work. From your posts here, I suspect that you do know these rules.When looking for feedback, consider the audience. Haveng recently been in your shoes I have found that the only worthwhile feedback is when people sit in rapt attention to one of my songs and when they applaud and ask to hear it again.
That being said, If you want to post some lyric for critism, I also would be glad to help if I can. Post something here or email me at robdale@mindspring.com
