My First Advanced Sig, well to me it was advanced. Took me about an hour because the background and the details were complex. As this is my first Sig posted here, I don't know what Cnc means, But Cnc it. Ps. This was made with Gimp and I'm a beginner. Also didn't know what to name is so feel free to leave suggestions.
CnC-Comment and Critique Text is bad: it is hard to read, does not match the color scheme of the rest of the sig, and is badly placed (as a rule, do not put text in the corner). Simple text near to the focal with similar color to the rest of the piece is usually your best bet. Background: Too busy, it draws the eye off the focal. Covers the focal, generally not a good idea. Flow is missing: there is no direction, the eye drifts randomly, and doesnt move in a preferred way. Color isnt uniform, and doesnt match the focal. Focal: Badly placed, the eye is not drawn to it. Considering the focal you used, it should most likely be placed to the left. Focal appears to be a floating helmet, which is generally an undesirable effect. Effects on top of helmet make coloring go off, and gives an odd appearance. I would recommend trying to use some tutorials.
