Get down what you can, and when you're ready for some help, there is a Share Your Work section here where the wonderful folks here will give you constructive criticism--and if you ask them to be brutal, they'll do that too.
*Check out Uncle Jim's thread. The tips and tricks you'll find there are wonderful*
Good luck!
