Grunewald retro, or the picture I posted? I mean yeah I guess people do not always draw like that today, although that is an actual problem with all the messy action and "modern drawings" (I think this is DC's fault mostly). I just love the color, the clear action, the high level of details. As far as Cap and being enthusiastic, I do not know, I just always saw him as so drab and obsessed with rules (kind of like Cyclops or something). In this one he just runs around kicking ass though, and trying to keep an apartment and secret identity actually does make that a little bit funnier / more relatable in a way that always being in costume and always being captain america will not do.
Also, I will be getting all the posts undeleted I am pretty sure, not that it matters as far as ruining the flow of conversation.
