I prefer seeing both eyes, but this is minor. Adding more definition to the abs and pecs is nice, but it doesn't yet quite pop still, it looks quite flat, you may need to examine/consult some guides or others on it, as the torso itself seems stiff as well. If you notice the first sprite has slight curves to it, which help show its angled direction (the way the character is facing). As far as the goods are concerned, I do not mind them being apparent, just covered, as public social norms would dictate, but of course modest proportions. Perhaps a balance could be made if you made the bulge from the first one slightly smaller/more concealed? Because in the second one, suddenly there is no trace of having a pair at all.
Only real concern/must I see is the torso area.
