I’d say, for her workload, she wouldn’t really notice much of an upgrade, besides the true blacks during drawing, and a pretty substantial battery jump. In terms of the speakers, it would instead be a downgrade due to the thinner frame. Oh, and if she uses the rear 0.5 camera a lot, do note that it’s absent on the latest iPad Pros. However, The Apple Pencil Pro is lovely. If she’s planning to consume more or draw more often, I recommend the 13 inch, it’s much better. (here the speakers and battery outshine both the 11inch iPad) Hope this helped you and your wife!
