Yeah, I changed the main body color, but the style will remain as this is an older model than the one pictured
More in line with this one: http://www.physics.mun.ca/~sps/serials/k.jpg
which is a "First Doctor" era dalek. A bit old to be messing about with the Fourth Doctor, but anything is possible
As for the coloring, I did make some changes and think it looks better. I also followed Mike's suggestion of smoothing it a bit, making it a tad more roundy without eliminating the whole "I found these bits in a rubbish bin...we have a critter!" look.
