An Amazing Train Station

The following paragraph is fictional. Would anyone be kind enough to correct the errors for me? Thanks!

Today was a sunny day, and I had an exciting visit at a grand, spectacular and imposing train station. I was fascinated by its magnificent appearance, whose wonderful workmanship excelling nature. I sat watching passengers bustle in and out of the train station. While I was gazing at the serene sky, a breeze blew over the station square. Riding on the wind, I flew into the train station. The interior of the train station, with superb, luxurious, and exquisite decorations, was having a nostalgic design and inspiration. However, it was overcrowded with travelers, and I was almost trod by the stream of people. Thankfully, my best friend, the wind, rescued me from the siege. It was a scary, amazing, and breathtaking adventure.
