Congratulations, Brian!
Good luck with the rewrites! And on future writing projects!
Congratulations, Brian! By finishing the first draft of your first script, you have made a massive leap in your creative adventure. It's no longer, "I want to write a screenplay." Now you can say, "I have written a screenplay." Yes, it needs work. All drafts do. But there is a world of difference for you standing on this side of a creative chasm when before you were standing on that side ... hoping you could find the wherewithal inside to do what you now have done!
Good luck with the rewrites! And on future writing projects!
