First of all, welcome to WCF! I love new faces!
Like Spencer said, definitely hit up other newcomers and see if they'll be interested in working a storyline. The more you show people that you're willing to put in work and create a HOT story at the same time? The more people are going to want to work with you.
As for your promos not being up to snuff, that's entirely subjective.
In my personal opinion, I can see a few issues right off the bat in terms of your promos and twitter interactions so far.
- Arch-Angel is a FACE but he kind of talks and acts like a HEEL. The way he calls everyone "imbeciles" who "refuse to see the truth in front of them" is a very HEEL thing to do. A FACE would say it more like, "you are in the dark and can't see the truth, but I'm here to shine a light on it", etc. etc. something along those lines.
- What are Arch-Angel's goals/motivations? He wants to win the World Championship, but everyone WANTS to win the World Championship. He wants to show everyone the truth. Give more clarification on these things.
- Cut out the huge font size. If it's something you do style wise for your promo, then by all means keep it, but (To me at least) it just makes it look like you're trying to make your promos look bigger. Quality over quantity is something you're going to hear a lot here.
The best thing about the WCF is there are A LOT of people willing to help. People will give you credit where credit is due and they will also tell you if something isn't working.
