I just grab the background and the title on google and joined it.
extract the file and copy the liteboot folder and replace the existent one on /usr/share/plymouth/themes.
RUN THIS IN TERMINAL TO UPDATE THE CHANGE.
sudo update-initramfs -u
NOTE THIS : I ONLY TESTED ON MY NETBOOK (1024X600)
if you notice the title is not in the right place create a new transparent image with your image editor like gimp or pinta with more height and copy the logo to there to satisfy your screen resolution. :)
