First of all, its great that you took the effort to use that old analog camera. In my oppinion, the first one is best. The moment was just right, a black and white version like this would look better then a colored one. The second photo has a big contrast. I think it is too big, you cant really focus on anything. (The man, or the sign?) The last 2 are abstract, turned out nice also. Do you have a digital camera also? (I thought you had one) Anyway, keep it up. Theyre great, people can learn from this.
