Window Seat/Storage

Ok, so I am a little nervous about my new latest and greatest design. I have come up with a really cute seat similar to the one below (I didn't want to post up my drawings because they are a bit hard to read) so thanks to Overstock.com I have this picture to show you instead. I am going to attampt to make this in one night. Do you think I can do it? I really really hope so, I was thinking of calling in some help, but my supportive husband said he believes in me and I can do it! And he will help me if I need it :)
I will post pictures of the whole process as it happens.
