I also got these placeholder PFP's and banners when I was still trying to figure out my style.
Though that implies I found it, I have not. Still iterating, still making stuff.

This one is literally just the mozt wazted font and I threw some random shit over it. Not my finest work but my first.

This is the second iteration of the previous one, this one was actually drawn by me and done without any external images and such. Or reference, for that matter. Definitely should start using reference, the N is the only letter here that I think actually looks good.

This one came after that, impact font with some vector editing and some random greeblies. Got a little excited about Marathon's art style, then I learned it was stolen from an artist called antireal and now I'm obsessed with their work instead. Still haven't figured out how to do that style though, I lack the abstract vision for it I think.

This one's an iteration of the previous one again, still exploring the scifi sharp-edged style. This one actually had some sketches though I lost them.

Nothing interesting about this one, I tried to figure out chromatic abberation in photoshop. It's messy and kind of shit. It's not used for anything.

Iteration of the other pointy N, had to simplify the design since I wanted it as a logo on my MC skin. Didn't have room for the connecting bar in the middle so out the window it went. I am now the Null Triangle Man.
My friend told me this was corporate dogshit, but I think it's grown on him.
Still trying to figure out how to do the rest of the letters in this style, turns out the U and L are conveniently some of the hardest letters to mess with since they're incredibly simple shapes. I'll crack it one day, I think.
And of course the signature, which was a throwup I sketched in about 20 minutes when I realized this site had them and I wanted one. I think it's cool, albeit a little boring. Now that I've got a drawing tablet I should probably redo it, but I've not really gotten good at getting consistent lines with it yet. Unsure on how to practice it as well.
