I see what you were going for here but the execution was poor and overdone. Remember one of the most important things in a sig is the clear definition of a focal. I can't really discern the focal. Also the sig is too messy. Not clean at all. The texture would be better if you didn't over do it so much. The color scheme is too dull and provides no vibrancy or contrast. Sig needs cleaning. Work on composition. Keep at it!
