Yeah, I they maybe Bachs got criticism for making Tim look too old/big in the first issue (which, imo, was not a big deal). Now he looks too young.
Tim is 17, going on 18. It's ok to make him start to look like a manling. Maybe keep the youth in his face somewhat, allow him to bulk up a little beyond his traditional frame, keep him a little under Dick's height for the time being... Why didn't they do this?
