I'm not trying to sound like a know-it-all (I've been exposed to some of those lately and hate it) so don't get mad at me. But what I noticed on this is there is no rhythmic definition. It's a very energetic piece and needs to have strong crisp attacks in the ostinato and those octave jump figures followed by the dotted notes. Also accents on the first notes of the repeated figures. The brass figures get lost near the end. Also the tempo seems slow. I've listened to the von Karajan performance of this to the point of wearing smooth an LP record, and it is almost maniacal in the intensity and energy. You have to get that into this performance.
Though it sounds good in a lot of ways and Bruckner is not easy to do I know. I don't think it would be too hard to get this more rhythmic - one easy way to get more definition (that I first heard of from Herb) is to use the dynamic samples instead of sustains even though the line might seem to use sustain. So sforzando and medium dynamic articulations combined with more staccato or portato would add a lot of definition.
