Too early to say really, you've made it clear you're just starting out. Some of your posing currently is pretty stiff and uninspiring but then it's also the case that you've worked with someone offering quite basic, and quite dated shots. Seems right now a typical case of suggesting you either work TF with or pay a much better photographer (possibly involving travelling a bit) to get not only really good pictures but a shoot environment where you'll be given good direction and a chance to show your real potential. Currently, your politely humble notes might leave you doing lots of pretty uninteresting TF that'll get you nowhere fast. Good luck though. I'm sure in the right situation you can improve your portfolio many times over in a short time if you play it smart.
Similar to what has been said already. Five of your images are very similar, head turning to left shoulder. Pity the weather is not good for photography for a while as I think an outside location and with someone sympathetic but maybe a bit 'assertive' giving you good starting directions, then you being willing to give it a go, yes some images will be rubbish but there is a stiffness and reticence in your posing at the moment, loosen up and take a chance.
