Concept designs:: bacteria

Some of the concept work I sent through to the client weeks ago, am now actually animating all these element's and needing to get it done before end of the month.  I wanted to submit something else tonight but I couldn't finish the piece.  Am exhausted.  Long days do take their toll and as much as I love keeping busy and doing all these projects, I do need a proper re-charge.  Will take the time to chill during the Christmas Break.  Mostly anyway.
