The sig itself looks great. The tree branches help add flow to it (in my opinion) but you may want to reposition or recolor the text so that you can actually read the word Embrace.
Weird colors, but that's just mean. Also, you need more depth. You did an awesome job of repositioning though.
It looks great but the colors dont really flow IMO. I say you should have stuck with the original color of the person on the new background.
The stock repositioning is awesome, but the only thing I noticed that wasn't mentioned above was the text. Consider repositioning it upwards slightly so that the word "Embrace" isn't blocked by the person on the left.
