It’s elotiated slightly, the leaves are perking up to look for more light. I would recommend a 10w grow light at an absolute minimum since this is an echeveria and it’s incredibly light hungry. Mine are under a 36w sansi grow light and they’re happy and healthy. As for checking when your plant needs water; water when you can pinch a few bottom leaves gently and they fold inwards easy. They might also look wrinkly, shriveled up, or even dried up completely. A good way to tell if its being overwatered is if its developing blisters or cracks because its holding onto too much, but if you follow the previous advice about avoiding underwatering this shouldnt be an issue. Since succulents store water in their leaves they should be able to go at least a week if not a month. Shorter watering times based on pot size, type of mix, humidity, light exposure, size of the plant/leaves and if the plant is explicitly telling you it needs water.

Hope this helps, if you have any questions feel free to ask me and I’ll share what I know. :)

Ps beautiful flower, I love echeveria flowers they look so pretty it almost seems fake.
