So, first of all I want to say that I really enjoyed the class. I rarely work with gradients so it was a great oportunity to practice with them.
I didn't save the references I used, but mostly I looked for sabers and more fancy swords (even thought about light sabers while creating the handle). I decided on doing this kind of long saber, I think of this as a sword used for very clean cuts and precise movements.
On this picture you can see a really rough sketch. I changed some details in the final drawing but overall it helped me a lot creating the concept previously.
And here is the final, I'm quite satisfied with the result. One thing that was really hard to achieve was the rounded look on the handle, and I also would like to add more of a metalic look to the blade (any tips on how to do this are very welcome :D).
