Help with my Cover letter?

I am trying to apply for a promotion to become a store manager. ive been working for the company as a assistant manager for a year now. please give me advice on my cover letter. What should i say what shouldn't i say!? please help me this is what i have so far;

As a current Full time Key-holder for solstice (philadelphia premium outlet) my goal is to grow within this company, I was pleased to learn that there is currently an opening for Store manager at Lenox Square mall and would very much like to be considered for the position. As a first step in the application process, I have completed an internal application for review.

With my current experience with solstice I have the opportunity to get a hands-on education of the solstice environment, brands and the company's expectations. Demonstrating strong leadership ability I do assist with the responsibilities of recruiting, interviewing and training of new talent. In my current role as well as in my previous roles with companies such as Cole haan, French Connection and BCBG Max aria I instituted new sales initiatives that increased the respective stores’ profits and overall productivity.

With my experience and skill-set, I feel like I can succeed as Store Manager and increase the profitability of that store.

I appreciate your consideration, and I look forward to hearing from you.
