That's good if the instructor can take her over a small fence or recommend a decent rider. Remember though, if the photos come back and she's not showing good form, or the rider isn't, I'd suggest leaving the jumping photo out.
The second photo is much better. But if she's in a nice bridle and under saddle (saddle should only suit the discipline she's suited for - or else it would look funny) it will definitely stand out more than the current photo. Also do you have a place on your property with spring flowers blossoming? A bit of colour in the photo would be more eye catching.
