I see it, I`m not sure the tiled overlay works..... would have been better to highlight the curve of the boot over the toe line using the dodge tool. Maybe a tip for next time
(Tip No.2 avoid using default PS patterns and filters unless really needed as they dont really get recognition on here)

You should pay more attention to a project an put more time in it, since this obiously isn't too good. But alright everyone has to begin somewere..
I recommend to read some tutorials. (written or video)
