Gauge:
Gauge is not critical but it’s important that stitches are close together and a bit tight (but not too much) so stuffing is not visible.

Use a stitch marker at the beginning of each round.
Read the pattern from beginning to end before you start crocheting. Becoming familiar with the terminology used and the layout of the pattern will ease your work.
