Yep, that's a decent start. And if you do choose to give it a go we're here to act as a sounding board.
Soemthing that really helped me not too long ago was looking through the Miniature / GW Appreciation threads here from the beginning. They're quite old now, 8 years or so IIIR, and some of the regulars have been posting their work throughout. Check out some of the people who are currently posting stellar work, and see what they were doing five years ago. It's a real push to see how some of the great painters here ahve improved over time because - and this is key - you will suck when you start. The important thing is not to be discouraged.
