Also web design is more difficult than logo design

This is your point of view, it's related to designers' specialties.
I saw web designers (as of myself) just import a UI framework and c/p the required components. It's about the effort designers choose to put in.

This is graphics section and I only evaluate the graphical part of the process, I didn't check the code part. If you think it's better suited for a web design process you should have tried development section instead.

I've just checked your 3 Pull Requests and it doesn't look like it started from zero, either. Even just by looking at the titles of pull requests.
