I will point out the obvious... Lots of listening to different Orchestras, bands, musicians and create an obsession...
Scales are important, but not the end of everything if you can't play them straight away! Make sure you get them in...
Also, if you rush you will F*uck up... I've sat with exercise 4 of Duncan McTier's daily exercises... for 2 months now... Let me tell you... Take care in the small aspects of your playing and for a fact, it will improve your playing tendfolds!! When I tackle sonta's or a new piece my intonation and shifts are with confidence and perfect intonation. All because I take care with the small things in my exercises... pay off, so when I'm playing the music I only have to worry about music and not the mechanics behind it...
