Thanks for the welcome. I'll definitely post up the artworks once they are finished

As for favourite, it's Optimus Prime, as common and generic as that obviously is. He is the character that I love the most. From his design, colours, and of course his persona. The sound his gun makes. And that amazing scene when 'The Touch' first kicks in when Prime lands on earth to stop the fight "Megatron must be stopped, no matter the cause"... into slow motion transformation and him going postal on the cons. I like that he's a reluctant warrior (he isn't so much like that in the three live action films, and in those I don't like him as much).

I also quite like Unicron and also Primus and wished that the notion/idea/character of Primus had been etched out in the G1 series, particularly when Unicron was around.
