What went wrong?

Those are my first two shots with my "new" Polaroid 1000 (for SX-70 film). I used a Impossible Project Sx-70 film and i shot them in the afternoon, on a sunny day. Few seconds after i took them, the paper became dark blue. Another few seconds and became pink. About 5 minutes later i was able to see the objects (the dog and me shoting myself). Aboute 15minutes later the process stoped and there was no more alterations! I I take the picture from myself 24h ago and the picture from the dog 20 minutes ago.

What went wrog? :( May you help me?
