sketchbook bro 6 (um pro)

just got sketchbook pro 6- wanted to see if it has some real upgrade- WOW- its cool to me- i especially like the zoom in feature with the pencil lines not getting too blurry as on sketchbook pro 2011-makes smooth clean lines simpler and the add of coptic colors and more brushes is a needed add- I noticed the added french curves and the control curve feature will make vehicles and smooth curve features easier- even my loose style is enhanced with this tool- cool beans
