DeviantArt- Question session part 1

The answers to some of the questions people have been asking me on my DA journal here; http://olafpriol.deviantart.com/journal/27479364/#comments though I know more have been added since I filmed this earlier today, so I may have to make another film later to finish them! Thanks to everyone for asking, hope I answer them sufficiently! Second part here: http://www.youtube.com/watch?v=3e8yJ2KTxOI
