Asking Feedback about the design of my website

Hello everyone,

I’m just starting my web development business and finished my website. I like some things about it but it looks a bit bald for me. Can you guys take a look at it and give me some advice or ideas on how I could make it more visually appealing but still style consistent?

Thank you so much in advance, I would really appreciate all your help!
