This is a great idea for this challenge, and the colour of the liquid inside the bulb is really funky and adds a lot of interest to the shot. I think that your execution of the idea leaves a little to be desired though. A few pointers which could really give this shot an edge are: Think about your background - I find yours in this picture to be quite distracting, the shadow, the blue surface and how it interacts with the white wall behind I find a bit off putting. The angle of the candle and bulb too makes me want to tilt my head. Overall, I give this a 4 - keep at it! :)
