Here to show my portfolio. I hope it falls into taste. https://codepen.io/StitchXtreme/full/PzraKx/
I think that it overall has all of the required elements.
However, I feel that the ‘About’ and ‘Portfolio’ headers are much too large. I also think that you don’t need the “Welcome to my website” part.
I like the menu, but you may wish to play with the colors as the menu gets a little lost.
Good job.
