Commenting only on this one. Being a newbie I find images like this one really hard to score. I have no knowledge of how they are made and the amount of work it takes to capture and create them. I would love to know more about the process so I can score them in the future. So, my feedback is unfortunately limited to saying that I think the flow of the colours, from the orange to the purple, looks really good :)
Nice overall color. Almost missed the intricate subtle design of thin light lines snaking along energetically. Wouldn't it be fun to have drinking straws imprinted to match the design on these two tubes?
