Ah kinda nice sigs. I like the first one. Nice matching colors.
I think the thing that is missing, especialy on the last one, is that you resize the render (stock) too much. Now they are not big enough and that makes your sig look empty. Maybe try to make your stock a bit bigger next time.
But nice job on the sigs.
