Back when the forum era was in full bloom, before all the social media platforms erupted, I used to do a lot of requests on my own forum for graphics. They were mainly for friends of mine whom I'd met on the forum, though I did get the occasional person who joined just to ask me to design something for them. Either way, I treated each of these requests as carefully as if I was designing for myself, meaning that I put in a ton of effort to make them look exactly the way the requester wanted.
I occasionally still take requests from friends though, to this day. Here are my very favorites, out of all those requests that I have designed for others.
