TS, after looking at your first and second posting, I have no idea where does sexy and gorgeous comes in for these two pics. While I give you the credit for willingness to learn, but these pics posted, I do not see any hint of sexiness or any gorgeous angles of the model.
Take #1. The hair is a mess. Is it because it is wet? The hand in hair pose here does not work. It just seems that she is only posing for the sake of doing so. Eyes are lifeless. They do not seem to portray any sexiness here, much less life. She seems bored at best. One major bugbear for me is the kneeling pose. For this pose, her stomach is protruding out and covering the top part of her shorts. Lest people think that this is a personal attack on the model, please look at the picture. A pose like that is simple but yet very delicate in the sense that the model has to suck it in and not let it all out. In this pose, it DEFINITELY does not flatter the model no matter how pretty she is. For a model to look good in that pose, she has to suck it in and hold till the shot is over. Where is the best feature of the model? That was not brought out in the picture. Suggestion is to try a 2/3 angle on the face rather than square.
For #2, slightly better than the first. But then again the eyes and expression, please do note that I still do not see any sexy and gorgeous you are trying to portray. Key here is to make the model alluring. But for the 2 pics, I do not see that. The figure in the 2 pics are full of straight lines. That does not make the model look sexy.
To me unfortunately, sad to say, these pics are not flattering the model. Even though you may be paying the model or the model is a friend of yours. The thing here is that the pictures you take of them should 1) flatter her and 2) accentuate her femininity. At the same time, a picture like this, especially a swimsuit shot, you as a photographer should help her see her beauty and not flaws. A swimsuit, especially a two piece one, DOES NOT hide flaws. It shows them. A word of advice: if you want to go into portraiture, try to shoot normal fashion first. Glamour shots where swimsuits are concerned, have a degree of difficulty where upon basics must be built. The basics should be normal fashion first before going into glamour shots.
