I think silver is giving some really good advice, especially concerning staying focused on projects. However, I feel like he is beating around the bush regarding probably the biggest issue. So... I'm going to critique your work. I've considered being all tactful and sweet in my approach, but everyone does that and it hides the truth instead of being honest. While I do appreciate your interest in modeling and your continued work towards being a 3D artist, your anatomy is terrifying. You are getting lost in all these superfluous skills without even a basic understanding of well... the basics. Modeling, rigging, texturing, are all a means to better express a core design and are useful in their own right, but without a solid foundation to work on you're essentially just polishing a turd.
If you were doing this strictly to have fun then by all means do whatever makes you happy. However, you mentioned you want to do freelance work at some point. Employers arent going to hire you because they want you to feel good. They will hire you because you have skills they need in their project. I wish the community would be more direct about this instead of patting you on the back, because if you don't learn this stuff now or it's going to bite you in the ass later.
I'm going to expand on silver's advice. You need to stay focused. I want you to google Miles Johnston. I used to hang out with him online back in the day when he was starting out. You can look up his old sketchbooks from 09'. He used to be garbage and to be fair, everyone starting out is garbage. However, he stayed focused on his craft. He along with some other people I knew, set their cross hairs on a target and pursued it. He didn't bounce around, he didnt take breaks. He and others like him worked hard and didnt give up. What does it mean to work hard? In his case that meant studying anatomy every. single. day. Learn from reference, study the reference, and then exercise what you learned. Like anything else, you will not simply magically become better if you just create stuff from imagination.
You need to learn, you need to do more studies. I would strongly suggest not even doing these studies in 3D. Pull out a pencil and paper (better yet buy a moleskine sketchbook), keep your stuff organized, and study regions of the body. Study the form of the body as you see it in the reference and ignore what you think you already know. Study regions of the body, from the bones to the muscles. Draw faces and heads, understand that there is a skull and muscles underneath that skin that gives form to the face. This needs to be done daily, the time and consistency you're will to put in will pay dividends down the line.
If you want to be a great modeler and you're serious about it then you need to have the foundations and you need to work for it. There is no other way around it. You're not competing against community.cgcookie, you're competing against the world and there are a lot artists out there who are absolutely hauling ass.
Anyway, that's the truth. If you want to compete you need to hone your craft.
