Processing problems, I'd suggest - sharpening after adding the border? Fine detail is lacking, and the composition is rough and ready at best. Colours are bland - lacking vibrancy. A poor go, I'm afraid.
Desplicts many textures and good effort. Needs to be more focused. Seeing more detail might bring out more texture. Keep shooting and keep from climbing trees to get a tennis ball down while playing tennis. Good luck
I verymuch like the composition of these several objects with pleasing textures and colors. There are some slight 'afterimages' that take some of the crispness away. Nevertheless, it is a very good rendition of the Challenge.
