Tony,
If there is one thing I've learnt about people who make things, it is we are all far too critical of our own work.
It looks heavy from above but not from the side, so you've achieved a depth of relief in the carving, probably in error but that does not make it wrong, it's a technique used by carvers all the time to make things appear to stand out further than the depth of the board they are working on.
Each of the swept curves looks the same to me, so that is a big plus point, and it's only your first attempt.
Keep it a few years, look back on it when you've done a few more and ask yourself the same questions about what you think is wrong again, you might be surprised at your own answers.
