Hans -
I prefer A over B, although I congratulate you in a successful completion of both pieces. I enjoy the contrasting woods in A and I prefer the top over B. I echo Gary's comments about the drawer pull. The pull in A invites the user to pull - just to see how it feels!
I also agree that B offers more of a mature feel, but I enjoy the lightness and casual feel of A.
Keep up the great work.
