Violin Answers

I have been playing piano for 11 years & guitar for 4. So, I decided on buying a beginners violin. I didn’t have much money to spare towards a violin so I bought one online from Crystalcello for 50 dollars. It worked well for the first week, but then the bridge snapped.
I then taped the bridge together so that I could keep practicing while I waited for another bridge in the mail. I decided on buying a new & more expensive bridge & better rosin.
The violin is very squeaky & makes a sort of ‘crunch’ sound. I was wondering if anyone would suggest anything else besides buying a ned bridge (if that alters or improves the sound at all). Would better strings make a difference as well? Or should I simply keep practicing my bowing?
Either way, my technique has improved & the squeaking has lessened, but I’d like to get rid of it completely.

why is it that when i play in the middle of the bridge of the violin the tone isn’t that nice, it kinda makes a whistling sound. That’s why i play near the fingerboard..

When I play my violin, I often get a squeaky sound when the bow runs across the strings. Most noticebly in the lower G/D/ strings… not as noticebe on the A & E; occasionally the A string makes the squeaky sound too.
I’m trying to play the solo part in Vivaldi’s Spring, instead of clear notes, i hear these squeaks & even screeching sound.
Any suggestions?
Thanks in advance.
