It looks pretty good, and I'd tend to say leave things as is if it's working for you both. But because of thet night wakings, it does seem that something maybe needs to be tweaked, there does appear that there is a big afternoon gap until bedtime and I wonder if she's getting overtired which can lead to a restless sleep at night. I can see that you need to get her nap in before you do the school run which can make it tricky, because the obvious solution would be to push out the two naps. But you're like me, I have a preschool run which messed with our mornign nap and consequently my dd got pushed onto one nap at 10mths as I couldn't fit two naps into the day properly. Do you think she's ready to stretch our her morning nap? And if so, could you time her 2nd nap with the school run in the car or buggy depending on how you pick your other dd up? If you can't fix the naps at the moment, I would suggest bringing in bedtime by 1/2 hr (or no later than 7pm) to see if she goes down a bit more rested and hopefully get some longer sleep stretches during the night.
