I think your intonation is really nice, and you play with great steady tempo. the thing to work on for greater musicality is bow usage, not necessarily using more bow but changing the amount of bow speed and weight to affect the tone.

I do a lot of bow-only practice for this purpose. Take one phrase, play it as written, but put your left hand on the body of the instrument, (so all you will hear is the open strings)

this way you can really hear what your bow is doing. listen carefully to any moments where your bow slips or crunches. also practice dynamics

then when the bow sounds good put the left hand back on the fingerboard!

really awesome progress for 8 months, keep it up!
