Enigmanaut

I've posted him here before, but I haven't drawn him for a good long while. This is my own character, Enigmanaut. I decided to draw a pic of him the other night for the hell of it. I'm probably leaning toward writing his story as a strictly prose adventure now... really never going to get my art to the point where I can tell it in sequentials... even a simple image like this took me a metric ass-load of time. But, I wanted to see what I can do these days.

It turned out fairly well, I think, though I only noticed that his right arm is too long after I'd finished it.

Any other crits?

... Oh, yeah... he normally has a helmet. Didn't draw it this time.
