Hi,
You've been posting a lot of works, but if you want them to be a kind of advertisement of your services and skills, I would recommend quality over quantity. In most of you images, there are some basic mistakes, such as stretched textures, repeating patterns, incorrectly applied textures, low-resolution backgrounds, and so on.
I would definitely advise either reviewing your images and posting only the ones you believe would serve as a portfolio, or moving most of your threads to the Work in Progress / Learner's Corner section.
