Still feeling this? Maybe I could help some.

Any advice? A friend of mine is helping me design right as I type but extra help is always welcome

Hmm. I'd say not to make it too complex. The design doesn't need to have symbols and chains and multiple layers of clothing with words and logos and such all over it. Mine, for example, is just a shirt, vest, and Aladdin-style pants! And I kept markings to a minimum. But I'm still recognizable, so you should be, too, even in simplicity.
And once you have your design down, you can tweak it later if you tire of it, so for now just settle for what comes to mind and see how it fairs.

A second tip I'd say would be more the practicals of it. If you're looking to customize things I'd recommend just focussing on: Body type (fat, buff, athletic/skinny-lean) fur color/patterns, height, feet (plantigrade or digigrade), claws (and their color), and hair if you want it. Oh, and eye color!
I'd recommend making it close to your own body type/style but you can lean more towards your ideal body type/style as well! And once you have your idea down, stick with it and don't fret! Or slowly change it over time, as you change!

Thank you so much ^.^

Sure thing, dude!

It depends on the person really! ^^ My fursona has been the same since I usually like to keep consistency. She's had tiny tweaks like spots on her legs being removed, and a white stripe in between the dark and light brown on her ears, but I don't usually like drastic change and I like to cling to how things are.

Others like you embrace change, or grow bored of things being samey for a long time. You may just like hot fresh new things and become disinterested in any one design staying the same for way too long. For you it might get boring seeing art of the same character, and you wanna spice it up with something new that you've never tried before. Sometimes it also has to do with self critique, or wanting to disconnect with something a certain part of a character reminds you of or represents.

It's not even that I get bored. I know he's gonna change and grow as I do, but he didn't even have a base design until my friend helped me recently. I just want him to be perfect, and any design I have ever thought of just never seemed good enough

Dante...Dante was originally Just a plain grey husky. Nothing special, not one ot stand out....its how i felt as a person....but i realized im not like everyone else, fuck the norms and suddenly ended up with a fuckton of markings.

XD I have a fursona that is like that, pretty plain like myself. But Domian is special, he's his own character and being, and I want him to be special like I think he is

you have ot understand your character is an extension of yourself. what you put in is what you get you know?

Yeah, well I've been putting in effort for 9 years, I should get a lot but I don't

Dom isn't an extension of me, he's my best friend. My own fursona is an extension of me, but Dom is separate entirely of my thoughts and feelings
