Here is a screenshot of my next new phpbb3 style. Its v2 of Board Reloaded's default style Radhe. Its about 60% completed. After completion of this style we are gonna release Radhe v1 for our forum members.
The box at the right part of top blue header is a bit too much to the right that it's gonna get out of the blue header. Move it to the center a bit.
The blue widget box theme doesn't match the new theme yet.
The last column in category (containing last poster and last post date/time) maybe will be better to be stretched until the end of the table so there won't be any empty spot after that last column.
I'd also suggest changing the forum icons. It's the default, and even though it matches the new theme, having something different from the default theme will be great.
Thanks for your suggestions phio_chan. I will definitely look after them.As i said before its 60% completed so many changes are still there to do including forum markers and that widget box.
