That's very good for a first try :D
Although it's best to not go heavy on the effects, especially the one you used, because it means that you're going to lose the focus of the image —scizor, in this case. If, say, you had erased the effect a little around the head and parts "closer" to the viewer, it would have given it a nice clarity.
:D looky i tried to make one by myself :P I think it turned out a little blurry and too confusing, but its still good for a first try, whatcha think? ;D
