Originally I copied a grand piano I found on youtube that was very clever, unfortunatly it was just too big to fit. I then found a smaller version but it was missing aspects like the open top and the pedals (not that you can see the pedals but they are upside down grey hammers - that idea came from the large piano).

Drum kit was pretty much original, quick image search on google for general shape.

I'm pretty impressed with the wine rack, thats a completely original design. Slightly awkward to get it all positioned as the program doesn't let you place pieces on top of others if they don't actually connect. So I had to use extra pieces to get the wine bottle in place which I then deleted after.
