The girl is certainly cute enough. Her skin looks a little flat. Perhaps that's just the lighting. Some of the built-in skins are good, but not great. Try some of Riddler's skin presets. 8K skins aren't really necessary, IMO. 4K is fine. Some of the built-in skins are OK, but you have less control with them. There are plenty of free skin textures available on the hub.
When you're packaging the var, please try to reduce the dependencies to a minimum. Any hair or clothing asset should come from the original creator, not somebody else's scene. The package builder will pull in the entire scene as dependencies. Make sure all the assets you use are hub-hosted. That will increase your visibility. The package builder creates a .txt file with the dependencies. You don't need to post that anymore, but it's worth looking at. If there are any WTF items in there, check how they got in there. Good luck!
