visual art Digital Backgrounds (Critic wanted)

[TopazReshiram 26]

Some of my Digital background art that I made in my free time. I would very much appreciate it if I could get some critic on these works.

I really like the second one, very interesting and artistic. the last one is nice also but i find the 2 rainbow ones a little too generic.

I certainly find the first two astonishing, they're just... amazing. Please make more of these, they're like drugs for my eyes. Keep it up
