Sentinel-mental feelings

I love combing through old comics to find the characters that just seem to pop out and cry for me to do a head shot of them. The Sentinels are the most recent to be penned to bristol. The classic "Kirby-esq" shape to their square heads and the ridiculous flower petal collar make them an easy choice for me. I always thought the Sentinels could be played up much stronger just as in the Days of Future Past run on the X-men. But sadly they were always played down.
Now that I look at them again...don't they look like that old Scooby Doo villain from the opening credits??....hmmm...
