Later in the process, I was tasked with coming up with some preliminary designs for a character called Princess Merpony. I didn't have a lot to go on at the time, so I literally starting creating a pony/mermaid character before moving on to an 'undersea warrior'. This was a lot of fun.
I created some very early versions of the Lego Movie 2 film logo. Judging by what the final logo looks like, I can only assume these were used internally at WB.
