There was a difference, when you ask for critique on the apparent, you're going to get it. When you say wait awhile until there is something to critique, then that is when your going to get it. In addition I'm counting all of the colors, black, white, gray, dark grey, green, and all the colors I will come across. So yes the color count will be high, but the truth is, do you care about a number or do you care about the product?
I'd rather fix something early than carrying an error until the end and having to rework stuff, so posting early WIPs is rather recommended.
But according to what you said, why are you posting something not yet crit worthy/something you don't want comments on yet? You might aswell keep to yourself until we can say something about it
As for Number vs Product, personally I don't care about either for this. But since you are posting on these forums for critique, I'll give the technique priority.
It just looks like you picked random colors out of a photo.
While right now we practically don't have any restriction, it kind of kills part of pixel art's nature (which in my opinion is to make the most out of the least, if you get what I mean)
But anyway good luck with further working.
