One of the main reasons as to why people really do this type of tattooing is because they want to unravel a story that they are trying to give off. For example, I have seen a famous soccer player that carries a full arm tattoo and his tattoo signifies what he loves, which is soccer and the love for his country.

However when you post a job for a custom tattoo design online you will frequently have 5 or more artists all bidding to do the work for you. Having more artists means you are more likely to find a tattoo artists that better fits with the style of tattoo design that you are looking for. Further more as we all know when people compete for your business you get better quality at a lower price.
Most local tattoo shops have two or three tattoo artists at the most. So when you go to your local shop and ask them to design a custom tattoo for you you often are limited to only the two artists or so that work at that parlor. Sure this is okay but if you think about it only two artists is pretty limiting. Each tattoo artist has their own unique style it is after all. So you are limited to getting the look and feel of the tattoos artists that work in the shop.
