Thanks erwinx. Points noted.erwinx said:1. the pics are unnecessarily large and difficult to view
2. Your sharpest pic is no.2, the others are on the soft side
3. pic no.4 the yellow on the breast seems badly clipped - huge amounts of posterisation.
so overall, pic 2 has the most potential, so keep on trying. If you want more detailed advice, you should give full exif details.
