how can i revise this or what should i look for to revise this: To begin with, I know that the designer for this freelance job would need to consider a dimensional look. As I have a Web design and interactive media associate degree, I do have experience in basic Web design screen and graphic design, basic Web scripting, as well as Web systems management and structure. I feel that I could accomplish quite a dimensional look for the client. I have included projects in my career portfolio to show that I have the ability to successfully complete the freelance project from Seven Designs. I have good design skills and I am very interested in getting practical experience building Web sites with this company.

What is this? One paragraph in a cover letter for a resume? Or what? It'll help if I know what this is part of.

This is a students freelance essayImagine that the paragraph below was submitted for part III of the proposal project. Knowing what you do about paragraph structure, word choice, and audience, offer a critique that will help this student to improve his or her work. Remember to be detailed in your response. How would you advise this student?

I have no idea what "part III of the proposal project" is. It would help to know that. I take it that "I" in the paragraph is the student you need to advise, right?

I'd get rid of the possible and insert a factual type of verb -- get rid of "would" and use present tense.

As I have a Web design and interactive media associate degree, I do have experience in basic Web design screen and graphic design, basic Web scripting, as well as Web systems management and structure.
This is long and a little awkward (that introductory clause), but has details (which are good).

I feel that I could accomplish quite a dimensional look for the client.
"feel"?? It's better to base thoughts on beliefs, not feelings. "quite a dimensional look" = 2 dimensions? 3 dimensions? what?

I have included projects in my career portfolio to show that I have the ability to successfully complete the freelance project from Seven Designs.
seems OK

I have good design skills and I am very interested in getting practical experience building Web sites with this company.
comma needed for this compound sentence; seems a bit weak for being the conclusion. And you'd need to doublecheck, but I don't think "Web" needs the capital W anymore.

I'd also get rid of "To begin with" -- it's unnecessary.

To revise this, here are some suggestions:

First, it is important to clarify your sentence structure and avoid using repetitive phrases.
