nice shots
#1 nice composition
#2 i find the door and clutter to the left to be distracting maybe eliminating these or taking a position witrh cleaer lines would lead the eye more to the fan
#3 i really want to see the face in this shot maybe a position infront wiating for the rotation to come to you. the biggest thiong with action shots is the face and expression of the people without these it may as well be dummies
#4 nice new perspective on an old location the hardest thing to do sometimes is photograph somehwere that is often photographed and make itr good but this works
#5 again i'm abit distrated in this there is alot happening maybe bringing the the apeture down to wide open would introduce some bokeh and give more of a point of focus
