I used a Stadler HB pencil for the sketch up.
A Artline 0.1mm felt pen for outlines.
Then I used Faber Castel coloured pencils for the colouring and shading.
This is my original Halo fan art so please dont discredit my work because thats not cool.
I do not own Halo or any rights to the franchise.
Just a big fan.
