Your own engine?! Wow, that's incredible. Is this gonna be like Servo where people can build a browser around this, or will it be a standalone browser?

I recently switched from Arc to Helium but it's still Chrome with different paint. When I was using Opera 12, it was the most standards-compliant browser so it became my main. What are the goals for cwbrowser (and is the name permanent)?

This is cool! And as someone else who's been building their own browser engine: welcome to the club!

Do you have WPT tests results, and/or screenshots of it rendering real websites?

Modern browsers should no longer score 100 on Acid 3 though. >By April 2017, the updated specifications had diverged from the test such that the latest versions of Google Chrome, Safari and Mozilla Firefox no longer pass the test as written

https://github.com/web-platform-tests/wpt/commits/master/aci... shows the history of the web-platform-tests copy of WPT, which has mostly followed Hixie’s earlier updates to Acid3 by simply commenting out assertions that no longer match what specs say.
