Buen hecho! Few suggestions I have.
- Try changing your color schema. Having a different background color for each section in your page is not a good idea. In general you should have a theme. https://www.websitebuilderexpert.com/designing-websites/how-to-choose-color-for-your-website/
- Don’t use default font. Use fonts from this helpful site. https://fonts.google.com/
- Your images are broken. Use a different source to host your images. You can upload your images to your own github repo and link them from there.
- Make it mobile responsive.
Cheers 
Add this at the beginning of your CSS:
html {
scroll-behavior: smooth;
}
Also try to stick to just two or three base colors plus an accent color(s). Take any professional site as an example (let’s say amazon.com) - how many colors can you see there?
Tanks for the advices i will work on that, and about mobile responsive alredy tried and i can’t with the images, 
tank you, i will change it, what is for the scroll-behavior???
Click on the links in the nav bar after adding it 
ohhhh i din’t know about that tag, its cool tank you
