Portrait for a DW project

It took a while to finish it, because:

1) I made a sketch
2) I choosed the colors carefully ("Which one is a good color for the shadow? And which colors are good for the scarf/the waistcoat?" etc.)
3) It took a few hours until the colors dried...the paint application is thick....
4) The background..."Which background? What shall I paint? Which colors?" Then I thought "He's a traveller through time and space...ah! The dark blue colors are the 'stream of time'...and the black squares are 'windows to space' (sounds a bit odd, I know...)
5) The shape, no, better - the size! - of the pic...I painted it on large -sized paper and I had to minimize it (thank goodness there are copy-shops ^^).

I hope you like it.
