Beech Bark Inspired by Nature Art No.1

Today is a failed technical image just to show that the iPhone does have it's limitations (due to sensor size) if you end up cropping an image.   I like to take photos of textures, especially different tree barks. This image is a beech tree which has a more smooth bark than the oaks, hickory, etc.  It was interesting because I found some inspired by nature artwork. Whether this is weather, disease, insect related??? This image is not sharp and pixelated**. I tried various in camera apps, but the best I could do was using PSE 11 and doing "smart fix". ** First of all there is no ability to take the image as a RAW image on an iPhone, the sensor is small, and if you crop the image to show more detail, then you will lose clarity and begin to see pixelation. i.e. the image is not sharp and can apprear jagged even if you did use a tripod. I did not use a tripod which is recommended for close up or macro shots..  This circle was probably 3 inches in diameter.  I was trying to get close but hoped to get some detail of the bark surrounding the textured circle as smaller cracks were present which I did not notice when I was taking the image.  The image has some blueish cast because it was taken late afternoon in a shaded wooded area.  An LED screen can be misleading as to the details of the image.
