Hi Melodie
Sorry for the wait, I was busy.
Well you waited for me too, and I couldn't help it. Don't worry I know how it is. I am glad to have you here bring your ideas and help.
I think it looks good, except for these few points.
1. Difference between icons 'New posts' (dark orange) and 'No New posts' (light orange) is not pronounced enough. I would maybe use the html background-color: 'lime' which is a bright green for New posts. It is easy to see and complements the orange.
Then if you use lime, or any kind of green, please reuse a bit of any of the green tones which are already in the banner, and check that the colors look nice together (can you do a screenshot on a test image and do that with gimp, inkscape or so?)
I guess you know color pickers such as gcolor2?
Also, the black borders around the orange icons look a bit 'clunky', they could be made to look more smooth and glassy and 3d.
Well I am at risk to look picky, however "smooth and 3d" is ok with me, glassy isn't that much. I know a few members who would not like it, so if some gradient effect can be done to make it look consistant, I agree with that. Let's try to avoid these old glassy effects.
I don't want the black borders either, I just did a fast "select by colors" and "poor some other color", using Gimp. I told you, I am not a graphist. (I just have an eye for colors, and the original colors of this theme seem much too strong and agressive to me, then also I feel the need for bits of hot colors red tones, but not too dark and so on).
2. Zooming in on the tabs, I see that the gradient colour is 2 steps red/orange, it would be nicer to use css3 and produce a sort of gradient effect, though not all browsers are html5 and css3 capable. Or change the code to use images for the tabs and then all older browsers will render complex 'artistic tabs'. I prefer to use css tabs rather than images because css loads faster than images.
We can try either or, as you wish. Then you will need to check how it renders in Firefox, Opera, Midori, and Chromium Browser. Nowadays these are the main browser (let's forget about IE). Also the forum isn't responsive and I suppose it's not possible to make it responsive? What do you think?
3. The banner looks ok. The background gradient is ok.
The banner could be enlarged to fill the full page width and blend in and be more integrated..
4. Experiment with thin borders, they can transform a page from unfinished and ordinary to very professional looking.
I agree completely. I don't know how to do that. Is it your main professional occupation?
