Pictures of snow are tricky and here it seems to make this picture a triffle to overexposed. Are there ice needles on the bluish window! They are my favorite subject;-) Missing them this winter. But nice shot!
seems a little over sharp, and I have to rely on your title to tell me that this is in fact a school, otherwise I don't see a connection to the challenge theme, maybe if you had captured some students walking with books, or included the school sign, I do like the perspective with including the fence though:)
Good job with the exposure (snow can be tricky) and composition is pretty good too. A bit too documentary though for my taste and lacking the human element of education.
