I personally hate it mate, the emboss or paint tube effect around the chinese writing lets it down, and if you look at the picture, on the bottom right corner it cuts off and leaves a straight line.
Ways to make it better in my opinion?
Get rid of the effect around the writing, or atleast make it a bit thinner and a bit more tidy.
Make the signature size smaller, go for the average size of around 410 x 110.
Not a bad effort though,
4/10.
