This is a really great start! It is very advanced indeed, however, I would change the styling a bit, maybe move away from Times New Roman and choose a more modern font. Also, you may want to change your color scheme, it is a bit too basic. I’ll link some resources below:
For coolors.co, just click “Generate” in the top right. They will walk you through it.
For Google Fonts, click the font you want, then click embed, and finally, copy the code you want.
Hope this helps!
