Don’t get discouraged by the opposite opinions. You did a very nice job with the icons, I hope more icons could be replaced so people who would agree to have less eye-popping icons (that they maybe rarely use anyway) but have a calmer interface will buy your theme. - I’m talking about icons inside panels and such. I bought it just out of curiosity, but I’m not a fan of the dark Rhino theme, so I will try it again once you will craft a light theme.
Demanding a complete UI appearance overhaul is one extreme, but defending the status quo and doing nothing about the clown panel is another. This is the most patchwork piece of GUI I have ever seen. It looks like every row was done by a different person and they were merged 5 minutes before the deadline 
But hey, the sliders are sliding.
There is a lot of aligning work to do in the Rhino UI, sometimes it’s hurting aesthetics and sometimes usability. And no one can do it besides McNeel. Various padding and thicknesses of elements were slowly improved over time, but there are still many hours of fiddling with it to be done. I hope it’s not being worked on by the same people who write more critical/strategic things.
This one below was pushed to the Rhino 9
There are also purely usability problems/wishes.
Since we have containers now. Every panel should be designed to be comfortable in a small, docked version and a big floating one. Select Color dialog is maybe even trying to be too smart in adjusting to different sizes
This happened when they wanted to change the Clown Panel.
