Okay, not to be totally negative about it, but I can't really say I like it, aesthetically or functionally.
First of all, IT IS SO SLOW. As soon as I started using roundedblue, everything became slower, and by a very large amount. I'm pretty sure it taking at least fifteen seconds for even "Random page" to produce something. I didn't have this issue with Monobook.
The font seems to have changed as well, for the worse. I don't like how the text is now larger, bold now pops more/takes up more space than before, and headers of pages blend in way too much--plus, they just look too subtle. One thing to be fixed is to revert the fonttype to the Monobook form. Also, the tabs in infoboxes seem to be affected as well; the only indicator of the selected tab is an outline, which I find far inferior to the previous box outline.
And is it just me, or are the headers seemingly oversized too (especially the  text)?
Furthermore, the tabs above that say edit, discussion, move, and so forth aren't even connected to the article, and float awkwardly. Then, when you hover over them, the tab itself disappears--that just simply looks bad, as though something is wrong. Similarly, in the top bar, the microscope looks rather atrocious, all pixelated. Is it possible to maybe extract an image used by another wiki using a microscope? I'm not very fond of the placement of our logo either--it doesn't do it much justice to have our big TVA image to the right, and then have our actual logo that links back to the wiki in the very corner of the page, looking very diminished. I'm not sure if it would look any better centered, so it may be just be the banner art.
Now, the side bar is also an issue. I quite liked the expandable side bar we had on Monaco, pre-Oasis. I thought that we were planning on retrieving this design for the new skin. As far as the boxes, they have no consistency in header font. The header font also, in my opinion, should be something more formal, and less playful--the latter of which pertains to its current state.
This is the big one for me: images. In all of the thumbnail images, a horrid white box surrounds the image, looking awkward, as though something is incorrectly sized or placed. And then, oh, the galleries. I weep for them in this skin. All the images now have TWO boxes surrounding them--one as before, another surrounding the direct borders of the image. As if this wasn't bad enough, hovering over them will sometimes produce a blue line that dashes through the image.
Summary: DoorToNothing found a lot of problems. Like, really, a lot.</Azul>
