Y'know, the cowl would actually look OK on Tim if they'd just cut off the top of it. Give him one of those Kid Flash-type cowls that cover everything except the top of the head. That would be much more Robinish (it'd look something like the adult Earth-2 Robin, if nothing else), and it'd give him the boyish touch which we associate with Tim. Picture it. See? Much better. And yes, pretty cover. Nice artwork.
