Hey, I hope you don't mind some feedback.
First of all, check your spelling on your portfolio. "Renders" should be without an apostrophe, and capitalize your I's.
Then, when posting 3D models, people will want to see technical info about them, as well: wireframes, polycounts, things like that. Looking at the models you've posted, I would consider them much too high poly for game development, unless you want to work in renders, in which case, show your renders. Texture them, as well, or get someone to texture them and give them credit.
Hope you don't see this as aggressive or anything bad, I just want to help you improve your chances. Good luck!
