There's a point where you cram so much in, that from somewhat up close, it doesn't look good, it only looks good if you're really close. Some of Taroni's sets are like that, along with clockwork8 and many others. This is fairly up close in the screenshots and it just looks messy, I understand if it looks messy from far away, but this has too many similar colors and not many contradicting colors to show off. Shading looks good, mapping looks pretty nice.
Not saying that it doesn't look good, just, it could have a little more contradicting colors to contrast the other colors and bring out some beauty in it, other than looking like one of those stained glass windows you see in a church with more grayscale colors though.
