Picture In header

Saw the new picture on my header?
I took it from a manga called "Beelzebub"
Then, I coloured it!
It took me quite some time,
since it's my first time colouring on computer using a mouse.
I just use the most basic "Paint" that everybody has.
Anyway,
I like the sea part the best.
The place where I used the many different colours.
If I'm not mistaken there are 14 colours for the sea.
I mixed the colours with numbers though.
The hardest part is the sky,
because I kept changing the sky's colour.
You could see from Kunieda Aoi(the girl)'s hair,
the shades of other blue.
I used 3 colours mainly for the sky.
I tried spraying on the sky.
And the words,
Originally from the picture itself.
Hope you like my new header picture!! :D
