brown foilage

Any opinions on what is wrong with my Juniper Bonsai and if it is savable? I have had this tree for a little less than a year. Got it from Brussel's as a birthday gift last August and now that the spring time has rolled around it is starting to brown on all of the edges. I did keep it outside...

Over the last couple of weeks my beautiful tree has been turning yellow and browning at the tips. I've been in constant care for this tree since I got it and now I'm not sure what is happening. Is anyone familiar with this coloring and cause?

Hey I was wondering what type of bonsai this is and if it is dead. thanks :)
