scince no one is giving you some cnc , lemme give it a crack First Sig v3 is the best but the left side feels a little empty but i like it without text. the green and blue colours go well together but the effect / c4d on the right side 's colour is off because of a orangish tint it has Second Sig v3 is the best again , it doesnt seem text is your strong suit just yet imho , i say get rid of the scanlines / shape tool and it would be a solid sig Third Sig i find this more of a step backwards in your case, i like the pentooling but i think it was over did and im starting to see just a bunch random shapes instead of a design. The lighting seems a tad off and that shape in the top right corner seems out of place. I say go back to your old style but dont be afraid to experiment and maybe find a middle ground Overall i like your work , you show a lot of potential.
