Those are still pretty good.

I couldn't do any better, I'll tell ya that.
One thing I would recommend is to play with yor temp a little more. The scratching looks very grainy, like someone sprinkled salt over the ice or something. I think there's nicer scratch/snow textures available in the ice temps made for for 05-09, and you can copy them right off there, turned at a 90* angle, onto your 2004 temp. Worth at least looking into, IMO.
