Rough Sketches

Yesterday was my first tutorial and we were to present our 4 rough sketches and 2 full scale to the whole class.

Here's my 2 full scale rough sketches:
After adding some colours :)I wanted to use the first design as I think its rather cute.
However, jing said that i seems like a cheery person, why do i want to portray myself in such negative light.
The colour of my work is also quite bright, communicating 'like' more than 'hate'.
The wonders of colour to communicate what we want people to know:)
I do have some ideas how to change my design a little to fit ME, MYSELF and I now.
will post soon! :)
