My first portfolio, would love some feedback please

Hello, its taking me about 2 weeks to complete this project, i spent probably an hour each day (due to work)
I picked up Sass to help organize my code, I really like what Sass brings to the table. I struggled the most making a nav bar too look decent. Eventually ill make the drop down menu different. I have zero projects done so there is just place holder images in the areas where projects will soon to be. I made the portfolio responsive for mobile and desktop. Any feedback is appreciated. Thank you.
