Alright, I decide to be as 1x on scale. I guess it doesn't hurt :D

Well, except the green man. It's too small.

The forum also has a zoom feature, so there's no reason to post larger thna 1x. On the forum, click to zoom in, ctrl+click to zoom out.

If you want to post on other forums though, I recommend using imgur or something like that. PJ has a lot of downtime. And on imgur no one's going to complain if they're 2x xP

For what I know, these images don't violate any rules established by PixelJoint. So it shouldn't have any problem.

But in case the images get rejected, I'll add them again in scale x1.

Thanks for your concern.

You should rescale it to x1 because it's a general rule of the resource, you know.

Not your personal portfolio folder or stock for forum images, actually.

Thanks for the advices and compliments :D . The colors were already defined before I touch it, so I worked with them.

About the scale, I'm posting them as 2x with the objective to use them in the portfolio post. Unfortunately, PixelJoint's forum rejects Dropbox's images and I don't want to use Imgur for it. So I'm uploading those images in the gallery, as I saw some pixel artists have done the same.

I can rescale them as 1x, but I'll have to do it with all the images and, as I use them in multiple forums, I don't want to make a bulk of the same images in different sizes.

I will write a state about the scale. Thanks!

I think the trunk is too thick for a willow crown of that size, I'd make it 3-4 pixels narrower.

The foliage looks gorgeous. I don't think I've seen that sort of technique before, it's very effective! The only tweak I'd recommend is making the less-saturated mid-green a little darker or a little bluer, currently it almost blends with the more saturated mid-green, its effect is a bit too subtle.

Also, any chance of a 1x upload? 2x seems unnecessary for this piece since it's fairly big, and it'd be nice to see how that foliage looks at 1x.
Edit: This goes for all of your recent submissions. Unless a piece is so tiny that it's uncomfortable small to click as a preview image, there's no need to upload at anything other than 1x. If you prefer the way your work looks at 2x, state so in the description, but let viewers make their own decisions.
