ok, here's some detailed constructive advice.
loads of girls i see entering the so-called modelling industry are not in it to be serious when it comes to modelling. there are 2 main traits here - the first includes a craving for quick money, hourly rate relatively high compared to what these girls can do outside of modelling. the second involves (sorry i couldn't put it any other way) a thirst for attention.
these 2 traits in combination can result in a lack of self-respect. this is what leads to all the scandals you see being trivialised in newspapers, girls stripping and regretting later on, girls placing themselves into compromising situations, or girls even agreeing to silly things that affect them negatively in the long run like sex for money.
i think the best advice anyone here will give you here is to think long and hard. is it easy money? maybe. are you really rendered more beautiful or desirable by becoming a model? i would really think not. just don't step into this messy arena thinking that you will reap nothing but benefits. at the end of the day, don't lose sight of the fact that this is an area where loads of predators hang out, in part because of previous examples being easy prey, in part because the current examples are also easy prey. you will have to be streetsmart to remain relatively unscathed.
predators don't just come in the form that will pressurize you to get into bed with them. there are those with honeyed tongues that will coax you into making decisions against your own thinking mind. as much as it will be your own fault, i think most girls would not just easily shed off their clothes for a photoshoot without such gentle prodding, especially in a conservative society like singapore. it takes two hands to clap. so stick to your guns, have a clear mind. just because the photographer is handsome, charming, whatever.. or he takes beautiful photographs of you, it doesn't mean that you owe him that much to take off your clothes if you are not comfortable with it.
of course, if you are entirely aware of the consequences, positive and negative - and there will always be negative connotations when people know that xxx has stripped in front of the camera before, like it or not.. and you are still comfortable then you have every right to do what you want. just make sure it is for the right reasons, and not because a handsome face with nice gentle honeyed tones and promises of a glamorous future is telling you that that is what he wants.
to minimize damage, suggest you do a thorough search on the background of photographer you engage before you step into participation with shooting with him. as much as some rumours are started by jealous rivals, there will not be smoke without any fire. you can easily do a search.

also, when you step into this industry, please don't think it is just about smiling, doing victory poses to succeed, if you are entirely serious. this will only work for a quick buck. in the long run, if you are serious you will need a lot more than just acting cute to be a famous face.
