I like what you have done but can you shade the cube in the center lighter or darker and shade the behind it a the opposite, kinda like
#74 is but not as drastic. Also can you try pitting the letters all together and make one word one color and the other word another but keep the like how you have it and make the E solid, by that I mean not have the center line be separated from the rest of it but still have the line cutting through.
Thanks
