DESIGN PRINCIPLES. Image and Frame

I was in group 3. We got a task to go round college and photograph circle objects. I really enjoyed the task because I miss photography quite often and it was an opportunity to wonder around college and 'spy' on other courses.  I was looking for a deep contrast, forms from shadows and contrast of colours. Circle was quite easy because You can find the  round form all over the college.

These are the 5 images that my group chose from my sheet:

And these are the rest of the pictures:
