Galaball

At my school it is the custom that a person who is doing his/her senior year, designs the poster for the Galaball at the end of the year. This is what I came up with after I got the permission to be this years designer.
Of Course I still have to add the word "Galaball" but I thought I would be better to upload it here without it.

this is a painting made with acrylic paint,
it is about 55 X 40 cm or 21.7 X 15.7 inch
The picture I used as a reference is lost... meaning that I can't find it anywhere on DA anymore, while I am sure to have put it between my favorites. If anyone perhaps knows where it is, please let me know so I can put up a link
