My pinterest board has a couple different themes that I am trying to explore. One is the hand relief that would be pretty three dimensional. I remember when I was a kid, we had this toy that was tiny metal pins you could push to make the image on the other side (I'll attach a picture so you know what I'm talking about). I like how in some of the pins I found, it showed the hand coming up through water.. I tried to quickly sketch something like that in my sketchbook. Another theme I was interested in was a colorful abstract piece using nails and either rubber bands or yarn (I pinned a really simple example of the principle of what I mean). I would use those abstract pieces that I pinned as inspiration to make a colorful landscape (almost) with a lot of dimension and a smooth texture. I also thought that the 2D/3D approach might be cool, as the pin the zebra and ship suggest, so that it would be a 3 dimensional sculpture, but it would also have some perspective so that it looked even more 3D from a specific angle.
