Lots of charm here, but for me number 8 has a somehow bookish charm (in terms of its head), but I like the body of 1 - could you consider a combination?
Indeed but will still what other people think as well so that I can develop and combine different ideas but Thank You Phil will try this as well :)
I like 8 and 6 personally. PhotoShop Phil gave me really valuable advise on creating silhouettes, you should give him a visit, he may gave you a different perspective :)
I like 6 and 8 too. However, don't forget this is meant to be a friendly sidekick character that helps within the game. Knowing this may effect your choice. Remember 'Fun, Friendly, and Helpful' are the themes.
Thank you all for the feedback I shall reflect on this and experiment further :)
