It is a great start. With Veileds you do not want to have any fake plants in the enclosure. They will start to chew on them which can pose an impaction risk. Females can be particularly motivated when it comes to plant eating. They seem to try to strip down their plants more then most males will.
For UVB make sure there is an unobstructed path down to the branches below it. Any plants live or fake if they are in between the branch and the UVB above it will block the UVB from passing through.
For most females having the lay bin farther to the back can be better. They do not like being within view when they do try to start digging.
With the window being behind the cage... Keep in mind if this window gets direct sun even with the curtains pulled it will heat up the ambient air quite a bit. This will be the same issue having the cage right next to a vent on the floor. It will mess with your ambient levels cooling or heating them.
