took me 2 days, probably about 10 hours I think. I have never used UVlayout before so took some time to learn that. You can't really say its hard, because every 3d project is the same. You set yourself a goal and then you trial and error your way to victory, if you have a problem you fix it, if you need to learn something you go find a tutorial and learn it. It is really time consuming work but its fun.
