Wow dude that's some pretty tight work. (you are improving). I like it, but take a suggestion?
Draw (on paper) a concept art (of an object or creature) or two. Then scan them onto a computer. Now make a model based on your concept art. Post both your concept drawings and your resulting model into a thread like this.
You might not see the practical application of this, but around here we will. It's a way of proving how good you are at the design process. Also, (if you want to go even further in that direction) consider uploading one of the models you've made in .blend format. That way we can download it and see how efficient (or otherwise) your work is. That's what I'd do, anyway, if I wanted to prove myself to a development team.
