These are nice! The contrast of colors in all of them is great, and I like the first one the best. The pictures, as a whole, have a great feel to them and they aren't too cliche. One thing I might suggest is that if you ever model your sister (Or anyone, for that matter) Try to get them to show more expression so they aren't just standing their with vacant eyes. In some pictures the vacant look works, but for the most part, try to have your models show more intensity.
Hi there! This is really a cool work... First of all the girl is really pretty which makes your job so easy Then coming to your photography, you are really talented. The lighting and the colors are really good. Keep posting your works. Carry your camera always... All the best... Cheers..!!!
I think I like the first one the most soully based on the fact that it looks real. We have this angle that really lets us get a lot of movement from the subject. We get a good look at her posture, her eyes, her lips and teeth, as well as her collarbone, which are all really interesting parts of the human body to study and capture on film. This reminded me a lot of a few indie photographs I've looked at, so yeah. I really enjoy this one =]
The others are really good too, very interesting in terms of backgrounds and contrast, the first one is just my favorite so thats why I gave it a touch more attention when writing this review. So, in all, well done =]
