/ic/ - Artwork/Critique

Please no bullying, I can't paint yet, I'm learning now
I can do value studies but when i tried to render pic related by brain just failed so i put just the flat colors on it

First time I color anything, I tried really hard but I can't shake the feeling the colors are off (not compared to the ref just in general) because I hand picked them and I don't know a shit about complementary colors, color theory, and all that jazz i only know by name
I also tried slapping some values on it but gave up because clearly I can't handle that yet
Other than that any critique?
