Constructive Criticism Please

1) Its not a bad shot but its a standard landscape and the colours are a bit bland . Was there another perspective you could have looked for.

Have a read of these:

2) although the light is dull this has got potential IMO -  but yet again the composition is standard - if you were to return think about another way of framing the barn within the picture.

3) surprisingly this appears out of focus considering you took it at f8.

Keep shooting good luck
