Rafael draws the best Tim. Hands down. Same with Supergirl here (though, she kinda looks like Stephanie from the Robin/Spoiler special) He miraculously GETS the concept of age when it comes to teenagers having to look different than adults in comics and renders body types appropriately. Both look athletic without Tim looking like a meathead (and more like the geeky WASP that he is) and Supergirl wearing THAT belly shirt and not looking like her top's gonna pop off and coming across as adorable if not somewhat innocent.
I bet he'd draw a rad Red Robin and do that damn costume some justice. I always notice the little individual touches he gives people's costumes.
PAY ATTENTION TO ALBUQUERQUE OTHER DC ARTISTS - THIS IS HOW ITS DONE
