i think it looks good and its not so big..maybe you are finding it dark? but it will look much better in a few months once its properly settled into the skin and it will get lighter too .... i think its a great start, and incase you decide to continue it upwards, you can use some play with contrast and create a beautiful sleeve or half sleeve ....
honestly id just leave it for a while , let it grow on you, before making any rushed decisions...believe me, i made rushed decisions over and over before i learnt that lesson, and i've reached a point of no return with my tattoo that i dont like, and now its such a big part i hate, i dont even have laser as an option anymore coz there are just too may layers to deal with.
