I should get on Mob Psycho, but I've just watched Spy Family and Blue Lock.
Waiting for a few other ones to start back up, but I always love new recommendations

Newest one, that he didn't like for reasons unknown

Always feels bad when they don't tell you why you dont like it. Maybe he wanted a more bubbly/happy look and didn't like the dark/angry look. But he could have easily told you that.
MrPonds attempt was also pretty good but he didn't like that either..
Back when forums were much more commonplace I was always paranoid that people would just fish for attempts without paying and then use them in another forum. But I don't think that people use forums anymore.

It's really hard to get a good render of bulbasaur doing a semi-decent pose.
I thought he might like the grittier version because his current sig is a bit dark.
I was wrong... lol. I still don't know what he wants

You should make it so it looks like Broly is beating up bulbasaur

Bulbasaur is my favorite, lol. I couldn't do that.
I also definitely won't be putting more time into sigs for a person who gives no feedback

bulbasaur beating up broly, confirmed.

The newest one, though he hasn't been online since I posted, so I don't know if he likes it yet...

There is one thing a saiyan always eats.. HIS FRIES!

I stopped watching Yugioh when this guy started showing up, I hate his guts But they did a good job making him look scary.
As for the sig, I think it has quite a lot going on, a little too much for my tastes to be honest. That orange orb on the bottom right and the millenium ring behind Marek I could do without.
But as always you really hit the nail on the head giving the signature the feeling of the character, making it look scary and mysterious. But I have no idea who that blue guy on the right is.
Did he end up buying the sig from you?
