Abstract Thursday

Ingeborg has suggested a "Natural Abstract" for today's challenge, by which she means as little editing as possible.

So when I saw a farmer ploughing a field during my morning walk I grabbed a phone shot of the furrows. The light from the cloudy sky was very flat and boring so I did succumb to the temptation to add some contrast and some colour but that's the only editing I've done so I reckon I've stuck reasonably closely to the brief!
