Sketchbook ideas

So after some researching i had the idea for the robot character in my head, then came the part of putting it down on paper.. Starting with a few sketches of a Saint Bernard dog, i then when step by step changing parts and coming up with ideas to turn it into a robot.... The toy robot dogs that were around in the early 2000's were good inspiration and a good starting point.. From my sketchbook, there is a lot of doodling but it is very helpful towards getting my final piece..



My idea for the robodog is it not being overweight and with sagging skin like the actual dogs themselves, but more of a chiseled exterior like that of batman or possibly the character from i robot..
