The design may show some character (your words) and is artistic...but it has a very loose shape and no details to give it the longevity as a tattoo my opinion. All tattoos are going to fade. But tattoos made with a solid outline are still going to hold their shape and contrast on the skin once the colours start washing out.
There is ample discussion on LST and the internetz about the merits of watercolour design in tattooing and everyone has an opinion. At the end of the day though...if you love the design, go for it! That's what it's all about.
