Picture books are most often 32 pages long. Yours would be about 43 words per page. Much longer than any picture book I've seen. Most have anywhere from 1-30 words per page, and that 30 is the upper side of pushing it. Just to bring yours down to the "wordy" side of picture books would be something like cutting 500 words or more.
Your quickest way to cutting is the description. The words the agent / editors want to see are the actual story, not the description of what's happening. Scary crazy, I know, but there it is. The art director and artist will determine the art on the page. You can hint at what you want through subtle writing, but don't dictate every angle and image.
If the agent told you it was amazing, do whatever you have to so they love it and therefore can't help but sell the book for you.
