Feed back for my personal portfolio and a little help/advice

So I am seeking feedback on my personal portfolio project 2.0 I struggle with design, and colors so will keep tweaking for awhile But any thoughts and feedback is very appreciated.
I also posted this in HTML-CSS help I am struggling with this error message 2. The height of the welcome section should be equal to the height of the viewport. Believe it may be from my @media query Just lost.
