hey Sophy, welcome to GFY & welcome to ModelCentro, it´s nice to have another model here with the MC group
I´d recommend more photos in each set, say between 20 & 50 photos per set, you can use 15 of them for free fhg´s for your affiliates, these are most important towards sales & traffic.
I´d also recommend a new video update at least weekly, giving your paying fans a new video through out their terms, leading to long retention. I notice the video clips are 1 to 3 mins long, I suggest you also spend time, spend a few extra minutes per video, 5 to 10 mins is good, longer is better. A guy wants to get into you, enjoying a wank before the video is over. He can watch that same video again & maybe see the end of the scene the following month he stays with you then.
You´re always welcomed to hit me up in the MC forum or on twitter...
good luck with your site & your sales
