Peta,
You've done very well with this, very bold in what you have tackled and details to the bowl, we can all find spindles difficult at the very begining, but when you get into understanding the design and you take to re-fine the details, things get better, if I look back to some of the first I made...
... I shudder..

Both of Keith Rowley books, Woodturning, A Foundation Course, ISBN 1-86108-114-6 and Woodturning Projects, ISBN 1-86108-013-1. are three which has all the basics, which will aid to building up details and design within your work, when you master scale and turn smaller and finer, which comes with time.
Your doing well, keep up the good work.
