Yeah, hadn't realised how lacking in contrast they were til you mentioned. The two are actually almost the same height in real life (I've just freezeframed it at the bit where they're walking, and Danny's asking about whether he's fired two guns, etc). I /should/ make him fatter, though. Wasn't sure how far to push it initially. :p I'll see what else I can do about the symmetry (Angel's currently got his various holsters in place, but I'll differentiate the shotguns as per the movie), though for the next bit, I'm more than likely gonna try and do side-view platformish-style sprites of them, so the symmetry won't be such an issue.
Cheers for the comments, I'll get some fixes done in the morning.
