> I downloaded from pbooru and seeing what can be "saved" by edits. Let's start with this legoman Rainbow Dash cosplayer. Can I save him? Can I make him more appealing to the eye?
definitely Ponibooru stuff doesn´t particularly encourage me to do anything. I still have visions of those "jewels" published in the /go/ thread. *shivers

Anyway, let´s see what we can pull from there in this thread:

> The lines are too thin and the colors too flat with no shading for any cool bumps or 3dish effects. It's only a minor upgrade at best.
at least it hides the color combinations and adds a little bit of depth to the picture but it´s diminished by the lack of shadows.

> I tried adding some noise. It looks like it could work as part of something else distorted but on it's own it just feels like an unfinished element to something.
I don´t usually use the noise effect mostly because it works on very specific cases and here, it doesn´t seem to correspond with the material given.

> Lines are too thin to have fun with a lot of filters, like neon for example.
doesn´t your program have an option to corrode or dilute the lines or contours? I know about one that does that function.

Have no idea what it does but it removed the lines and gave it all a flat minimilist look that almost looks a bit appealing

I believe that I´ve got that same filter (watercolor) as well and yeah, it removes the lines  or little points drawn randomly in any picture. It depends on the level and how many layers you want of it to get rid of them and maybe your edit went too far at removing the lines that it carried the right eye of Legoman. Check out if there are any levels for that filter.

I still don´t know which edit to pick, probably the embossed one for me.
