I'm in the mood for a little bit of composition feedback!
I moved your characters more towards the center of the scene, think "rule of thirds" in photography. This also allows you to have fewer architectural lines splitting the drawing in two, which interrupts the read of the image. Having the corner of the room in the center of the image gives too much importance to the background and not enough to the story unfolding. It's also room for more legs, and legs are good 
I gave more importance to the Aphrodite character - she is still small but she needs to feature prominently as to not be erased as a background character. This may allow you to put an expression on her face, or grim omens around her such as a broken vase at her feet, injured servants, whatever!
I changed the shape of the door-way. The square shape currently interrupts the flow in the picture, and does not look particularly attractive for a palace - perhaps a balcony, some greek collumns, or a half-dome grand entrance would be best? Either way I think an arch frames Aphrodite better.
Finally, values. To increase the read of the picture, the planes of the image should be very clearly defined, and ideally have attractive silhouettes. The far plane is the exterior, the lightest part of the image. Then, as you get further from the exterior and closer to "us", the planes should be getting progressively darker. Paint your colors and value scheme with minimal contrast within these planes, but keep the planes contrasted with each other - this is the key to a complex scene that reads well.
Hope you like some of my suggestions! Either way it's your call in the end - I love where you're at currently
