Yes it's better this way, using an image host and [img] tags. It's important to save your pixel art in its original resolution, as PNG or GIF, never jpg. That way you preserve the crispness and the original palette, and others can edit your work (super helpful). On this forum you can click & ctrl+click to zoom images.
Ok first thought is nice flow with the hat, pose shows promise. And good job keeping your shapes clean and fairly readable.
What's detracting from it at this point is the proportions (legs in particular), and the features can be better defined, for example the eye sockets. That single white pixel at the bottom of the jacket is just noise. With this palette I'd use black and the pink more on the interior, because on a black background the white is really strong.
