Usually you have beer/wort on top layer, then yeast, then trub... That looks pretty good. Are you going to wash it again? Also, I have heard to only harvest yeast from a primary and not a secondary.
Personnaly I have had mixed experiences with harvested yeast... a few failures but more successes. Make sure to make a good starter before you pitch.
Good luck. Hope that helps.
And on the eighth day he said "Make beer!"
