The heavily tonemapped ones are mostly pretty awful, although the underlying photographs are pretty much pleasant scenes pretty well shot. Some people like that look, to be sure, but I don't and I think it's a fad that nobody will like any more, pretty soon. It definitely looks unnatural.
The old shoe is pretty solid work. Good choice there to pop the color up like crazy, and an interesting subject pretty well placed in the frame.
No technical issues like "you're not focusing right" or "exposures are all off".
