U.K. Army recruitment

Hi, I am looking to join the army and want to know my chances of getting in ??
I am 22, fairly fit, I have a lot of tattoos most are on my chest, arms and legs, but I do have a hand tattoo and another on the back of my neck.
I also suffer with asthma and eczema, both not too bad, but I do have to carry an inhaler, will any of these things hamper my application ???
