I like this photo it's a cute idea, the only thing I would have changed is zooming in to the tacks page so you could not see your windows task bar and the edge of your computer. this way the first things you looke as is the shoping list and the tacks.
... and the clock shows that those tacks better arrive within 58 minutes! Nice job being able to enter the challenge without the actual tools (tacks). I wish the upper part of the image wasn't crooked. The crop is nice though.
I' m generally not fond of shots which use the image on a computer screen as a major compositional element, and this is no exception. The note could use a touch more lighting from the front.
