Nice first try with the speedlites! I love the poses. However, I really think you should consider using a narrower depth of field on shots 1 and 4. A good background blur would really set the model off better. In your last shot the sky seems too blow. Now that you have the speedlites you have an opportunity to deal with this by overpowering the background. Take an AP shot of the sky, switch to the manual mode using those settings, take an shot of the sky, make adjustments to your liking, then move the model in and use your speedlites in the manual mode to properly expose her. I think you will be pleasantly suprised. There are many better experienced photographers on the forum that have a ton more experience the me that would be happy to chime as well. The main thing to remember is that you did a great job of experimenting and the posing was terrific. Good job!
