I don't know...you seem to somewhat grasp the technique behind art (and by that I mean, you know how to make something) but you do not seem to grasp art itself. You just randomly throw stuff you have 'learned' onto eachother and hope it looks great. I just noticed now, we have been telling you to use filters brushing and sharpening. You made a sig, Jakut didn't like it, so you sharpened the render, hoping the sig would look better.
You know how to make a signature, you just don't know how to make art. Making something, and making something look good are two very different things. You can learn to make something, but I don't think you can learn to make something look good.
Compare it to playing piano. Everyone can play a piano, but it takes a true artist to compose something that sounds good, Mozart for example was a real talent at composing.
After all our suggestions, you have learned how to create a signature, but you still haven't learned to 'compose' a good signature, to make it flow nice.
