Aside from the images not loading for me, as it says they have been moved or removed. It seems quite good for the first attempt! I have a few suggestions myself for how you could improve this, it is all constructive and you don’t have to do them if you don’t think what I am saying is correct! I do really like the post note you put on there that rotates as you hover over it nice touch!
- Change the font. Personally you want clean and simple, you can have it as your logo or titles but I wouldn’t recommend it for the rest. The content will become hard to read.
- The navigation highlight when hovering just needs a tad more impact so maybe go more grey when hovered.
That is all I have seeing as I cannot see what images you have used on the page. But for a first attempt for what I can see it is good, especially since you haven’t used any CSS library either.
