Hmmm, the shots have good angles, and I especially like the last one and the 3rd one, but I will give you some tips:
1st. Save the photos in superfine mode and directly to your pen drive (USB stick);
2nd. Don’t put the exposure so high, try to balance it, not to bright and not to dark, find a middle term;
3rd. If possible post in thumbnails linked to the full size pictures
The rest is good. Keep it up 👍
