Thank you for posting the photo of your project. I recommend waiting for the first render to dry off. This will prevent moisture from being trapped in the render and degrading its hold on the wall. When the render is dry, you can proceed to add another layer of render to reach your desired level. I suggest opening windows and doors to allow air to move around the area, this will prevent moisture from being trapped in the room. You're making excellent progress, please keep us updated.
If you need further assistance, please let us know.
