Looking for con-crit on my art

[DigitalPopsicle]

I've been in a really big art slump lately and it's because everything I wanna draw never turns out the way I want it.


So I'm looking for some con-crit on my artwork to try and improve myself, especially because I'm trying to do commissions for money at the moment.


Here's some examples of my art, all safe-for-work and most are links to Tumblr or deviantART, going from newest to oldest near enough:

1. [x]
   
2. [x]
   
3. [x]
   
4. [x]
   
5. [x]
   
6. [x]
   
7. [x]
   
8. [x]
   
9. [x]
   
10. [x]
    
11. [x]
    

Please be as honest as you can, I'm seriously looking to improve my artwork.
