Great. :3
Okayz! Here are a few super useful tips my very good at RPing brother told me:
1. If you want to make a bigger post, try to describe as much details as you can.
2. You use comma's (,) if you want to add something, and when you dont, add a full stop (.) (This one really helped me, i don't know if it will help u though)
3. Always make sure to preview ur post before u post it to make sure it's long enough.
4. Always double check ur posts for spelling check. ;)
And that's all i can think of right now, if there's anything else you need help with, just ask me. :3
