ROSA has been giving Mandriva based very attractive looking distros for quite sometime and their Desktop Fresh series was released last year in KDE, Gnome and LXDE spins (I am not sure whether they have any XFCE spin or not). My review is based on my experience with ROSA 2012 R1 Desktop Fresh LXDE for last 7 days.
ROSA's latest update comes with Linux kernel 3.8.12 and Openbox 3.5.0. PCManFM 1.1.0 is the default file manager. PCManFM is fast, lightweight and performs well in limited resources. Also, it provides majority of the functionalities expected from an advanced file manager.
ROSA LXDE desktop has the typical deep blue ROSA look with ROSA elementary themed icons and color combinations. The desktop looks really good but a bit empty. I like what they have done to PCManFM's interface. ROSA's PCManFM looks absolutely smashing!
