pretty nice, i like the lighting alot. I just find the focal point a lil' weak, I'm trying to look at the character, but gets distracted by the waves.
Other than the border and the position of the text, looks pretty nice to me. The top right-hand corner looks a bit awkward IMO. Gj though.
Yea, with the style of the signature I would blend the render in a bit more, but I really like the way it was done, and the color. Nice job m8
I would try and give it a more mysty effect try using the blur tool to do that then sharpen certain parts and keep doing that
