Sweet bluebird? ;-)

Some days ago Berroco gave out free pattern, called Bluebird. It was so sweet that I didn’t hesitate and made one. I used Catania yarn from Schachenmayr nomotta, 100% cotton, colours 0201, 0050 and 0208. Needle size 3 mm. But it didn’t turn out exactly as one in the pattern…
I have problems to understand how the parts should be sewed together. Both when I made the elephant and now with the bird.
