Might have over-compensated for the shadows. lol

Believe I figured out a better way to create the dot mask by running G'MIC's b/w dither and using that result to run Shapism. :)

I really like this one... How do you make something like this?(Maybe I missed something)

In G'MIC, there is a preset (under Art subdirectory) called Shapism. The problem with that preset is it usually yields unfocused results. I use another G'MIC preset called b/w dither and feed that into Shapism instead (using transparent background color instead of the default black). Create a mask by chosing Alpha to Selection and highlighting the GIMP toggle selection option, I copy that and then untoggle and selection none. I then paste for the mask. I then run Threashold (moving slider left to brighten) for the mask and run Blend (Shape Average) with original image (Blend (Shape Average) is located in Testing folder>Lylejk; David saved this preset for me when he went another direction with the preset; I like the original behavior better, and definitely appreciate that David saved this preset under the Testing section). I then add layer mask and past the mask in that to smooth out the dots. Maybe the programmer gurus here can automate this flow. I do use a copy of the threshold mask and apply a convolution layered dot set to grain merge to push more details, but that's part of the secret sauce I use. lol

Create the convoluton layer by duplicating the original, and on the base layer I run Sharpen (Gradient) and set the top layer to Grain extract and merge down. I then used Blend (Shape Average) on the convolution layer with the threshold mask as mentioned to convert it to dots which I then set to Grain Merge over the colored dot result. This step, again, adds more perceived contrast/details to the dots as a whole (globally that is). :)

Oops, :oops: I didn't do your last step

by the way, How do you choose transparency instead of black?

Also, you used original as base layer which gives you more perceived details (but cheating). lol

Nice birdy, though. :)

Also, wasn't going to share this Gorilla, but why not. Only a clickable link to see it (and didn't want to start yet another thread). lol

OK; will share Mufasa with you all; working on bringing out finer details such as the whiskers; still a work in progress. :)

Really cool results Pix/Sallyanne. Instead of using dither, I tried using Stamp with 50% grain and got ever closer results to what I'm going for (not sharing those plays since I'm still tweaking). :)

edit (12 minutes later).

OK, here's the same tiger using the new masking technique (and increased the big dot size to 50 from 35). :)
