Very clean lizard. I think she does look a bit obese, you may want to cut back on the food.
I have blackthroats, a larger version of monitor, but this is what works for me.
I try to feed mainly whole prey, as it's just a easily balanced diet. For young ones, I fed nearly every day in small meals, but as adults, I changed to feeding two to three times a week. I feed smaller or larger amounts, according to their currant weight gain.

The old tried and true rule is "Keep them hot, and feed them lots" to grow monitors, but you do have to limit their food when they get nearly full size, as they will become obese quite easily.
Hope this helps.
