This logo looks good! Was it actually from Photoshop? You can never know with AI existing and being better now. How long did it take to make this logo?
Judging by the title, the user is imposing that this is “Vector Art”, which isn’t exactly known for using gradients.
It may just be low image quality, but I’m seeing a lot of gradients on this logo, which means it isn’t vector art, and since OP claimed it to be vector art, I’m doubting either that they made it, or that they are an artist. If an artist would use AI for some reason, they’d at least be able to list the style correctly.
Even though OP didn’t list the style correctly and the images pretty blatant AI look, I’m not going to say with 100% confidence it is AI generated, I’m just going to say its very likely.
I will also say, there is a chance that the gradients exist due to an insane amount of post-processing done to the image (that I’d argue ruins vector arts style) and that the line thickness inconsistencies are just a stylistic choice, I however cannot place my finger on any possible reason for the 2 Ds to be different from eachother.
There’s nothing wrong with creating something with AI. Although don’t lie and say you did something in another way. Sure some devs frown upon the usage of AI but hey at least you’re creating something…
