I found an old edit I did back in mid 2024 https://files.catbox.moe/0sbv2l.jpg
I've made hundreds of edits at this point, but when I made that one (again on my phone, but using a different app) I'd made no more than a dozen. So here's something you could try, a little art exercise using the same artist:
>Decensor this image (use whatever program you're trying to get better with)
>Add simple smegma blobs like the ones I did here >>11352351 around the edge of the glans (blobs being 2-5 circle shapes combined)
>Make them big and add an outline to fit nishikun's art style
>Smear and fog are optional, because they don't really fit the style
>Bonus points: add a highlight of shadow to the smegma blobs
