C & C Constructive Criticism

Please give people constructive criticism Not one or two words saying it sucks or Something along those lines.
The idea of giving out CnC To other people is to tell them what to improve on and what they can do to make it better, and if they start recieving this "Constructive Criticism" they will slowly start to improve knowing what to do as people have said to not do this or do that.If you do give bad CnC Guests and members will slowy Go away from this site as people are not telling them what to improve and keep saying that sucks if its a begginer tag Or there just starting making sigs. Not giving good CnC and giving bad ones they will quit because no one will tell him what to do or say posistive stuff. Im not saying it has to be Oh thats great when it isnt Just tell them whats wrong with it. So thank you for reading i hope to see more Constructive Criticism flying round.
