Also, I like this signature. Although, I would have to say that the bottom bit of it with the red and black doesn't seem to make the signature work very well together.
It's his. You can tell. It looks pretty cool actually, but really it's just a bunch of different net-downloaded brushes (I can see the red arrows in there, I have that set myself ) that vary in colour and opacity.
Like I said, it does still look quite nice indeed. Well done.
As far as Photoshop skills go, this hardly pushes the boat out, but it doesn't look too horrible. However I must say I'm really confused about why you chose that font and text placement.
You need to fix the fingers, text style and placement. I don't really know what to say about the fingers except, no. The font doesn't match neither does the placement. Try curving the text with the curve of the colours and make the text one solid different colour. Hope I wasn't too harsh
It's visually appealing tho, just small details that need to be fixed.
