i like the second one better, seems a cleaner design than the first one, and more balanced. considering lent is the 40 days until easter, i would stick with 4 lighter color candles (light purple, pink, or even a light green), and a taller white one in the middle. one candle to be lit every 10 days, and the white one on easter. inspired an idea that i'll forward to you, to see what you think (involves purpleheart).
