Request for edits to your avatar or pictures you want to use for your avatar here. I (or anybody who's willing) will fulfill request as closely as possible, usually when I'm bored. But I'll try to do around two to three requests every two days or so, unless a particular request is notably difficult. In general, I'll try to make the edits match the style of the source unless specified to do otherwise. I can do redraws, recolors, Photoshop edits, and gifs; I'll also make an avatar transparent if prompted. If somebody else has already completed your request, I'll only redo it myself if specifically asked to.
As usual, the more specific the better. It's also much easier to work if you provide a larger image, or at least the full-sized version of your avatar. I try to do edits in the order I receive them, but I'll inform you if I don't know how to fulfill a request and why. I won't do edits to pictures you don't intend to use as an avatar, but I may if you message me directly as to not clutter the thread. Furthermore, I'll be repurposing this thread whenever a new holiday comes around where people want their avatars changes to celebrate so I don't need to make a new one every now and then.
Here's some before/after examples from previous threads to demonstrate what you could potentially ask for (holiday theme optional).
That's effectively how. Grab some kind of photo editing software, practice, look up Youtube tutorials, and try to figure out what every tool and option does. If you're so inclined, you can dedicate an entire day per tool doing a project which specifically uses it. Your competence comes from familiarity first.
Recent GIMP is actually pretty good. I've had a hate-boner against it for a long time but now... it works. And it is free. Some usurper must have murdered the morons that made the old interface.
Photoshop is like 10-15 bucks a month so that's no big deal. Change e-mails and roll new VMs to get eternal trials if that's too much.
I like to use the most recent, although I haven't been keeping up with the latest version. The newer the better is generally my opinion of Photoshop, since features generally are improved rather than removed. It's a resource hog, though.
I can use Photoshop decently well, but I don't have a specific edit in mind. It might be fun if someone (anyone watching this thread, really) surprised me. I can reciprocate, if you want.
