Wow this is absolutely amazing i love just about everything about this work. I love the little things the ponies are doing that show there personality goes. Also Very Detailed with each pony on what there doing. In all honesty this is what i see a day in canterlot looks like, and the fact that everypony is doing something not just standing there makes this just so interesting to me. It makes me what to look at all the references from the show and make the connections to it. I think this is the best work i have seen in a long time. Great job and keep up the amazing work. /)
First of all, I must commend you on your originality. Inclusive art like this is actually very rare, as it is hard for most artists to have many things going on at once and still interconnect them. It is a great "snapshot" of ponydom, showing what a "day in the life" is for the denizens of equestria.
As for vision, it is not particularly groundbreaking in anyway in terms of style, arrangement, but it is particularly unique. Kudos.
Your technique could use improvement, but I suspect that this is either your art style, or just that you need to grow more as an artist, either way, promising stuff, I hope you continue to show the world you talent.
As for impact, nothing about this photo particularly moved me (But I am a tough critic, it takes a lot for me to cry). But it none the less is interesting and sucks you in to see all the little details that you put in there.
