Not bad. Im not a fan of the text however, and I think the render could be blended a bit better. Also, I personally think the render might be too contrasted a bit (the dark areas seem a bit too dark).
V1 is better. When I said I thought it was too contrasted I meant the render, not the whole sig. V2 just looks washed out. And Im not a fan of the 3 different fonts used for the text
