It's weird how you have all positive reviews, but the score is only 3.61. I guess that isn't bad, per se. It seems like all of these were kind of similar. I could sense a futuristic tone here. My favorite, by far, is the one on the far right. I just now notice all the vials it's holding.
In that sense, it isn't that futuristic. The colors, for some reason, remind me of Neon Genesis Evangelion. At first glance, they seemed to be made of the same material. I looked closer and realized that wasn't the case. Good for you and your creativity again.
