Yes... "so much to learn"... but having an 'eye for a picture' is a great start. Everything else can be learned (books... classes... etc...), but 'seeing' pix is a skill that a lot of people will just never get. And a bag full of hardware isn't going to compensate for that...
One thought... I used to shoot colour and b/w on film (one camera body for colour, another for b/w), which meant I'd look differently at a subject, depending on which film I was using. If you want to end up with b/w images, maybe you should shoot in b/w... rather than just 'converting' colour shots.
Not enough 'pop'? well, it's all about light, you know...
if these pix are from your second day's shooting, you'll have a steep learning curve. enjoy the ride...
