very nice indeed. you should give yourself a pat on the back for that as it looks brilliant!
I have 1 question.. the legs.. can you still get to them easily? I cant seem to see any drilled holes in the legs? Its not 100 % needed but advisable because if you have 2 small holes drilled into each supporting leg, this will allow water to pass through and thus the water inside will not go stagnant.
sorry if i didnt mention it before, it completely slipped my mind until i looked at the picture then. if you cannot get to th elegs then i dont think it will cause serious problems. Its just an observation on my part really.
