Note that each slide in the carousel has a different image, which needs to be replaced.
All the dimensions of all images should match the ones being replaced. Maintain the color scheme as-is, but I'm willing to accept suggestions if you really get inspired.
Bonus points if you can decrease the byte size of the images. For example the background image on the main page is very large, despite being a blurry background decoration. Theres probably room for optimization here. Maybe you can come up with a background that is nicer looking but also smaller?
