I always visit Amber's room when I can because of her personality. When I first became a premium and had tokens I'd visit random model rooms based off their pictures. Every room that I went into I'd get a PM from a model saying hi.
At first I thought it was nice they actually wanted to talk but then I just figured out they were trying to get money from me.
When I came into Amber's room I wasn't greeted by her because she was so busy talking to people which is fine. She never sent me a PM so I instantly felt like she wasn't out to just get my money. And to be honest she isn't. A lot of models sit there on cam and charge for a tit flash or something else.
I think the way Amber does it works awesome because she sets a goal to get her naked. I'm not sure how keen you are on that type of setup for your own show but it seems to work for her. Granted, I'd rather she stay in some sexy lingerie sometimes because she looks fucking amazing in it!
As others have stated if you are going to play music pick something generalized and don't have it too loud. You'll probably get a better response from people by talking instead of typing.
Oh and speak ENGLISH!!!! lol There are a lot of model's room that I never visit because I check their profile first and see that they are from some foreign country. I'm there to interact with the model and I'd prefer to be able to understand her!
For me, thumbnails/avatars have a lot to do with it as well. That is how I pic what model I am going to look at by looking at the avatars first then viewing their profile to find out more information. When I found Amber she had a bust shot including her face in a black bra. It was a great pic and showed off some of her assets while also showing her face. I don't like the models that show their tits in their avatar as I like a bit of anticipation.
Anyways....if you wanna hear more from my perspective let me know. For now this post is long enough! lol
