Looking at it, it looks pretty good. For a guy/gal just starting out, it looks really good.
If I had to be really nitpicky (and some of this is subjective) …
I find the color scheme a little nauseous. (But I am famous for horrible color choices, so what do I know.)
I think the blue is kind of in the middle ground in terms of darkness - black text is hard to read against it and white text is too.
I usually like a little border radius on the pictures to undo those sharp corners. I usually like it just barely noticeable. It would be like 5px in this case, but your padding is getting in the way. I’d do like
margin: 20px auto; and then apply the border radius. But that’s just me.
Your text. It’s so looooooooong. If someone goes fullscreen and a large monitor, it’s insane. There’s a principle in UX that text shouldn’t be more than 40-50 characters. I think you’re above 200 here. I might set a max width. I might also have put the list in two columns. The same problem with the quotes below.
I might center the last line.
I can’t find any major issues. There are little things - your last li is missing a closing tag - there is an extra div closing tag. Other than that I’d just say to get in the habit of formatting your code as you go. Use proper indenting and spacing. It makes it much more readable.
I’m not saying you need to make any of these changes. Go ahead and move on. Good job. On to the next task. I’m just pointing these out so you can use this knowledge on your next project.
