You have such amazing beautiful photographs and a lot of talent and passion for this art form (stalked your portfolio a bit). I really respect that you're a professional at this, but that signature/splashmark really ruins your photos for me.
I know why you've got it there, it makes sense, but it really takes away from this astonishing image for me.

Im sorry to leave such negative criticism about a small little detail, but this is honestly world class work or close too and the splash mark just irks me.
