I just started shooting as well.
I didn't do well the first time. In fact, I did so poorly I don't even want to tell you my score
But after some help and instruction from others, I did well the second time.
The more experienced shooters pretty much told me the same things:
1. both eyes open
2. point, don't aim
3. proper choke selection
4. something about stance and mount (their beautiful O/Us distracted me
5. something about swing/follow through
I'm sure I don't have everything listed, but I was told that those are fairly important.
If you want to get more technical, this book might be for you:
Hope that kind of helps
