Really awesome for your second !!
On my second sig i didn't know what clipping mask or even how to use brushes !
Good job for that
But i think you could blend a bit more ,an the text is nice but move it a little closer to your focal,and also like Splinter already said ,a bit to blurry
But nice job and keep going
And could i see your first sig ? If your 2nd sig is that good i'm wondering how your 1st sig was
