I think Walter's a great name.

(And don't worry about changing your name a million times, I've already done it 3 times in like what, a month or so that I've been here? lol)
As far as how much input I let people have on choosing, I originally went with a name that I had always loved, Braedon (and would've named my daughters if they'd been boys - who knows, they're young yet, one of them may ask for that name back some day... lol. But honestly, I hope not, their dad would *absolutely* blame me if either of them turned out to be trans (or queer of any flavor, really). Fingers crossed that they're both cis, straight, and "normal"...

).
After I'd tried out that name for awhile (on here, and with my partner), I came out to my mom and one of the first things she awesomely asked was "since you're not going to keep the name I picked for you, do I get any say on your new name?" So I asked "well, what would you choose if it was up to you?" and she picked James, which I really liked. I then talked to my brother (who I'm extremely close with and have been our whole lives) about what type of name he thinks I "seem" like, and he picked Steve. He even joked that no matter what name I went with, he'd still call me Steve anyways "cuz it's such an awesome name - everyone should be named Steve" (and no, it's not his name. lol).
So I played around with Braedon, James and Stephen in my mind for I think a week or two. A couple of times I'd be hanging out with my brother and say "hey, think quick: am I Braedon or James" (he went with James) or I'd look in the mirror and say "Hey Stephen, how's it going? Hey James, what's up? Morning Steve, how'd ya sleep? Can you pass the salt please, Braedon? 'Sup, Jay?" and just tested out how each of those names and nicknames felt.
Eventually I just got to a point where I felt really comfortable with James, and the others just weren't fitting. Also, I really like the fact that I can say "that's what my momma named me!" without resorting to fabrication.

So, that's the long and the short -- okay, okay, it's just the long -- of how I chose my name and who had influence and how much!
