Art without a doubt comes easier to some than others, I an definitely an other, but it doesn't mean that your never gonna be able to create beautiful pieces of work.
What I do is read as many books as I can find, watch as many great smiths as posible, wether in person or on video, spend lots of time on IFI, and practice, practice, practice and practice some more, get good at blacksmithing first, once you learn and know how to make things and how to make the metal do what you want it to then the creativeness will start to come naturally and you can start to work on it then.
It's just how I've done it and am still doing it and I can tell you that it will work or atleast it has for me, I'm still no artist by any means and likely never really will be but I am becomeing a pretty creative blacksmith.
