It seems...oversharpened. Tone down on that, because it detracts from the quality of the signature. It's an okay signature overall...better than your last, definitely.
I would like if some part of the sig was smudged, it seems way to oversharpened although that style fits this one very well making it not such a big problem. I really like this, I think you would do well with this style of sig making. Nice job
Better less sharpen. Now just sharpen the robot only, but not the arms. And if you could, erase some of the c4d over the robot. It seems messy.
