It is a completely valid style. (Holdsworth, Tom Quayle, Oliva and many more have used it). My only suggestion would be to work on your picking techniques as well. Great guitarists have options and then make choices. Give yourself options. Everything you learn is just another tool. HOWEVER – that being said – if you end up being a legato God without any other techniques – there are worse problems. lol
Find your bliss. Make cool sounds come from your guitar however you can. Above all – be happy and enjoy playing.
Cheers!
