Quickly I learnt that even the smallest mosaic pieces will fail to depict the details, and I had to choose one with less feature. Eventually this image from Pikmin Bloom, one of the screen image as you open the app, caught my eye. The hardest part would be the three fingers - we'll just have to wing it!

I started by putting mosaic pieces (50mm width sqaure) onto the wood board, to see how many pieces and what colours would work with my design. 

Some people start on putting the pieces on paper which would have been a smarter idea, as I would not need to mess the pattern that was already neatly on the board to put EVA glue on the surface, just to put the pieces back again, now all over the place. Lesson learnt!
