To be honest, I haven't had time to work on the picture. I've been in dire straits with this java/sql-program I needed to create for school, just barely made it, and I've had a whole lot of exams to attend. Worry not, I've got only two exams left (re-sitting the Java-exam and attending UML-exam) and after that, I don't need to worry about school this spring. I'll get working on the mask-version right away and carry on with the colouring.
Apologizing for the delay, yours cruelly,
