I see you are fairly new to DPC and are settling in nicely. Terrific.
When I first saw this iamge, I thought, wow, what an attractive model and expressive eyes. Then I went to the umbrella and finally to the scarf, which was, I think the main focus of your composition. This image almost works. (If it was mine, I'd be happy!) Nevertheless, there were some minor problems that come to mind.
Yes, I also think the umbrella is a tad 'heavy' for the composition. But if used, perhaps the model doesn't need to be holding the handle. Then, there is a little red x at the lower left that might be better out of there. I'm gonna really nit pic and say the tag on the model's scarf should go away. And finally, there's something about the model's dress, especially around the waistline that gives the appearance of being wrinkled.
I'm really being nit picky about a really good image, because overall I think you have an excellent start here.
So, keep 'em coming and I wish you much luck in your future photography. You really are good at this.
I see the model's beautiful gaze first before the scarf. Maybe the focus has been inconveniently shifted here. Similar colours between her hair and the scarf don't really help the scarf as the main subject of silky-smooth to stand out either. But like I said, the model has a beautiful gaze and maybe this picture would better suit a category like that? Interesting lighting by the way :)
the composition in this one is great but the post processing seems way off to me. this would be a job for advanced editing so that you could get smoothness in her skin with arbrush and clone brush instead of all that neatimage and you could get rid of the logo on the umbrella and put a more even light on her face
