This is a very good project. All the links and buttons work, color scheme is nice, I really like it. If I was to suggest any modifications there are two:
- Is it possible for you to style the file upload button? It's got the basic browser button styling and slightly clashes with the rest of the desing
- On the about us page, maybe you could consider using further styling to really set off the 'Who we are' text. Not sure, maybe lighter, darker, offset into bootstrap cards.
