Good job! I like the choice of the colors for your theme. Here are my suggestions.
Paragraph in about section. Too much text in small area is not good. I would make its width smaller and increase the font-size and line-height to make them bigger for more readability.
So are the description texts for your portfolio section. Do the same as above.
For more information contact section. I would bring it closer to the form to group them together.
I would center your social icons in the middle.
