The difference between stealing and using an idea as inspiration is that when you use an inspiration, you make it your own.
It is perfectly fine to use an idea if you change something with it
I used a dolphin on wheels because I thought that it looked really cool together
I used pencil as my medium because I wanted to work on my shading with pencil
If I can change one thing with my peice I would use a color pencil so I can show the colors
The most succeful thing about my peice was the shading
