honestly mate.. i'm going to speak..or to the more astute type to you as aone adult to another. I would practise with photoshop for a while, may it be hours, days or weeks. read tutorials on how to do certain aspects of design pertaining to kits.
Your first kit posting with no collar.. that would take me about 5 minutes to do, if not quicker. This is for your own benefit because if you don't practise and improve.. people will probably criticise and berate.
I am saying this for your own benefit. Please practise before posting a request thread, because you will get a fair few requests and you need to have a certain level of competance to fulfill the orders to a decent degree.
