Hi Gary

I've only been at this myself for about 20 months myself so at times I'm a little reticent to critique others. But here goes

What I can see is that you are bowing over the fingerboard. Try to bow 'about' halfway between the fingerboard and the bridge.

Try to use a bit more elbow and a little less shoulder

Try slowing the bow down a bit

It looks like you don't have much tension on your bow. The looser the bow hair is the easier it is to bow 2 strings rather than one (a good thing to remember when you move on to double stops) But too much may cause bow bounce. Play around with it.

You can play longer notes if you bow slower.

I hope there is something that you can use there

But its sounding good

How long have you been at it now?
