Credits to griffpatch for the tutorial. It took me 4 hours and 30 mins for ep 1, 2, 3, ,4 and 5( 4 hr and 30 mins all together) Each video was about 30 mins - 35, but I had to pause the video because he was to fast and I made mistakes so I had to do the whole episode again. I recommend doing the tutorial but not the whole 15 episodes / whole series, just up to episode 7 or mabye 10.
