Post it and see what happens. Our eagle-eyed admins will quickly spot anything out of step and comment/suggest as appropriate. Most of us had hiccups on our first attempts until we got the hang of things, so instant perfection very rare. If it looks right to you compared to how the film looks on your screen, it'll probably be OK, so take a brave pill and go for it!

And enjoy the process of being creative - it gets addictive .....
