I am not someone with a lot of personnality... Whenever I see a good idea, I feel like giving it a go...
You may remember Axiom and Colin recently had a go at creating little mutated creatures for rogue trader and this gave me the will to try to do some myself...
But why would one want to create small, weak, painful to watch, useless models ? Well because they sort of define the kind of setting you want for your games I guess. You want a world full of characterfull heroes ? Good for you. I do prefer (matter of taste) having a bit of everything making the average guys look handsome and villains making normal dudes look like heroes.
