Could you share with me some tips about that burning hand ? Look interesting :x

Well If I remember, I think you should draw the hand sketch first
1.when you finish to sketch hand, you draw a curly cirle surrounding the hand sketch (sorry I am not good in english and vocabulary)
but you must blurred the outside cirle and in the middle cirle you must not draw so dark in the hand sketch, just outside the hand. Just like that.
2.when you finish blurred the outside circle, use the eraser to erase for making the burning shape (use in corner eraser or use the small eraser)
3.Use your own finger to blurred the burning shape, just take an easy( don't torn the paper too much)

AND DONE ^^
I usely don't know how can I do it or how can I think that, LOL Don't ask me why because I just want to creative art of my own.Sometime I can use the brush too blurred, too.

I see , so its all about the eraser , hmmm , thanks for the tip , i'm trying it now :D

Look not so good but i think it has a bright future :x

your welcome and thx
