It's all a question of how many she can tolerate before she's sick of them/me. Since commissions are technically closed right now, it's a low priority for her, which I totally understand.
I sent her a list of all the remaining Disgaea/pony commissions I want from her (I wanted to let her pick), and I'm just waiting to hear which she wants to do, since I offered to pay more than the usual fee on two of them. One of those is due to complexity (Rozalin's dress is ornate!), and the other is due to multiple characters (what I asked for with the CMC would use the same class for all three, but different colors, the way Disgaea does ranks for classes).
Assuming she does all of them, it'd be a total of thirteen (the two she's done, plus 11 more).
