Critique my work

I would appreciate if any of you would critique my portfolio here is the link [weblinks removed as per forum guidelines] before you yell at me for having a [removed], keep in mind, it's easy and it's free and I've had it for years. Probably clue #1. 

That being said, please don't hold back I need honest feedback, i've been designing since 2004 and feel that my design reflects that.  I know my skills are a bit lacking, however, I just got a decline letter from Creative Market and they told me my design is not up to their standards.  Yea it hurt, but that's the name of the game of design.  I realize I got so discouraged over the years, that I gave up.  Then went back, would give up and would go back.  I'm not trying to give up anymore, not going to go back to school at this point I'm too old, what do I do?  I watch You Tube videos to help me gain knowledge on the tools, I've done freelance at first, but graphic design has come so far, I didn't keep up with the trends, now I'm trying to cram 10 years worth of industry design, into one year.  In other words, I'm trying to fit a square peg into a circle. Should I just keep learningn and pursuing it as a hobby, at this point and pray that people will actually hire me and take me seriously? I've had jobs that let me go because of my lack of skills, eg: tshirt design, and print shops and sign shops.  

Any help would be appreciated. I trust this community that's why I'm not afraid to post this here.
