Aww! Lily is so cute and looks really happy! There's no such thing as too much décor when it comes to chams, the more the better. I think the enclosure looks great, could add a couple more horizontal branches/dowels by using push pins through the screen to attach them. Are you cup feeding her? How old is she? I can't tell her size by the pic. Depending on her age you need to factor in space for an egg laying bin.
