Heres my tip... Uninstall Photoshop...
lmao, im kidding.
The red on the right corner doesnt match the signature at all. You have some nice flow and lighting going, but the light on your render needs to be a tad bit softer, so its not starting to distort the image.
You've got a good start there, give it some more attention, and it'll be solid.
i'd like to see a v2 if you ever get around to it.
