I like the improvement -- [righton]
Could you maybe put a gaussian blur on the wall shadow? (the shadow of the orb on the window wall) It kinda' looks like the orb should be cut in 1/2 then place about 1 inch from the wall the way you have the shadow set up! It should look a little blurred -- because in real life, light bends around objects. And the further you get away from a hard surface (such as a wall) the shadow becomes less defined and more blurry!
Also, I liked the way you had the lighting scheme in the first one. I like the new lighting scheme in the second one -- is there a way to possibly combine the two? What I mean is, keep the window bar shadows like the first one and meld them with the lighter color of the second one! It'll add some great dynamics to the picture!
Oh, before I forget, the second link doesn't work -- maybe you might want to get that fixed. I would like to see the tutorial for this!
But otherwise, I love the improvement you made on it!! Try those hints to see if it makes it look better to you!
