Hyh, 10 hours...it can be shorten by training. I'm currently colouring one of my work and I'm already in 50% done...after about 12 hours of work (and I've got only ponies coloured, no background yet). It is very entertaining job! I believe that the professional artists spend a sight less time on colouring their works.



Your work looks great - I can't even find a line which is not smooth. I imagined the skies as brighter, but those are good too. Keep up the good work!
