I like it, but with a few tweaks I could love it.
Although harder to find key caps, doing a split spacebar would really help with a design like this. Then you could have half the spacebar as enter instead of having the enter so far away. It's a key that gets used very often, so having it more easily accessible would be handy.
And if you don't want to do a split spacebar, I would move the enter key where the Win key is, move the Win key one to the right, shift the entire top row from ; to ] one to the left, and then put the question mark between ] and \.
I would also swap Ctrl and Fn on the left, that way Ctrl is where it normally is and would haven no learning curve, and Caps would just become Fn.
