Looks OK, maybe too many shades of colour but nothing painful on the eyes.
g-fox, I must say, as a fellow graphic designer, I don't understand why many people are so mad to have 'artfully simple' signatures, such as yours:

This is very simple compared to JCCs, there is little to look at, but I know there is a lot of work in your sig, the small touches, but I don't understand why so many people love these, I prefer a nice bit of brushing, more like JCC's than your own, I know empty spaces can look good, but there seems to be a need for them quite often.
I like JCC's signature due to the fact that I can see the work put into it, and though it isn't amazing, to me it represents a good honest siggy, compared to these pretentious (not directed) signatures that seem to be big, I do make some myself, but I prefer signatures more in line with JCC's here.
