TF shoots are an awesome tool for building your portfolio, but for a beginner like yourself I think you'd benefit from first hiring a professional to give your portfolio a backbone. You can learn more from those who really know what they're doing than you can from someone at your same level. Does that make sense?
On to critique.
Compare these images side by side.
Make note of the difference good context can make. I prefer the image on the left and I'll tell you why: it's a picture of you. I see your eyes and I perceive that you're present and thinking about something that engages you. Conversely, the image on the right shows you looking off to your left as if a cat is wandering by and you're nervous about it touching you. By the way you are holding the purse by your chin it's almost like you're thinking about eating it like a sandwich.
Lighting, composition, and set design aren't your responsibility. Your job as a model is to make it work. And in the left image, that's exactly what you did. Find more photographers who can help you hone that skill and you'll go places.
I hope this is helpful. Good luck!
