Has anyone made this pattern, Stacks 3 whirligig design? I started to cut the fabric yesterday. I am now wondering if I may have gotten in over my head.

Just wondering if it is difficult or am I just being paranoid as it is really out of my comfort zone. Have had the pattern for awhile and am trying to get things made that have been stored in the to do pattern box for awhile. I think this will take me some time to get done. I know that this pattern is a tumble block, which I have never done. Here is a pic of the pattern front.
