Anyone got any dialouge tips?

Yes!
Dialogue is hard to write, it takes practise, don't give up fast.

a) If one character will fill another character in on a 最近 event, don't retell what happened, it might lose the reader. Say something like "Anne filled Ronnie in on the events of last night"
b) If あなた have a big number of characters,say 10, talking, try not to only have 1 character talking, thought all might be too much. Also make sure each character has his/her own voice. A catchline, way of speaking, accent ('Eet iz an honnor').

Well, there are a few things あなた can do.

-Know your character well, and think how they would speak. Everyone talks a little differently, so what would they say? For example, if it's a four 年 old child you're putting dialogue in for, don't say things like, "manifestation", "lobotomy", "phenomena", etc... unless they are really super-intelligent four 年 olds. What would a four 年 old say? They might be whiny. They might be shy. They might stutter and talk もっと見る like "I w-w-wanna go t-too!"

-Don't just say "He said" and "She said". Use different things. あなた can use "said" too, but don't overuse it. A few things あなた could use besides "said":
Replied
Squeaked
Chirped
Piped
Groaned
Mumbled
Muttered
Hissed
Choked
Coughed
Cooed
Stammered
Spat
Giggled
Demanded
They all set a different mood for whatever they are saying, giving the dialogue もっと見る colour and もっと見る life.

-Add some movement. For example, let's say あなた were 書く and it was a whiny, typical stereotype teenage girl あなた were having speak. あなた can have things like, "...she mocked, rolling her eyes" または "...she challenged, raising an eyebrow" That gives a clear picture and further sets the mood and shows off the nature of your character.

Hope I helped! :)
