I know this is a request, but looking at this I honestly believe you are capable of saving this sprite yourself. I promise it's not as bad as you probably think it is!
I definitely think a look at A&D's pixel art tutorial will help you out here. It doesn't cover things like Pokemon sprites in detail, but it'll give you a good sense of the fundamentals of all pixel art - like the rules that all pixel art follows. You need to start at the basics and work your way up, just like baking a cake! It won't do if you don't have all the ingredients and follow the right steps, after all!
Looking at your current trainer sprite, I think one of the best ways you can improve it is to make sure your pencil tool is set to 1px. You've got pixels of varying sizes in there and when working in such a small area every detail counts! You need to maximize the space available to you and be mindful of the more important elements of your character so they translate well.
Once you get more comfortable with general pixel art, I think testing out some recolors will be good for you. Just take an existing trainer sprite whose pose and whatnot match your character the closest and start playing with the colors. Maybe change little details here and there. Get comfortable with making edits and color changes before building from scratch. This will give you a good feel for what a Pokemon trainer sprite really consists of. That, and you won't have to worry about things like proper anatomy right away. Recoloring is a very valuable tool in learning how trainer sprite are outlined and organized, and will give you a sense of how to replicate it when making your own. Take it slow and practice, practice, practice! :)
Thanks for the heartfelt response, it really means a lot and actually inspires me to give it another shot!
I was getting really frustrated because I could NOT get it the way I wanted, but for sake of experience I will keep trying. I originally used Gary Oaks sprite and kinda kept the outline and modified it a tiny bit to sort of match what I wanted, though it came out looking like a ditto experiment gone wrong :P.
I use MS-Paint, as when I try using Photoshop it always comes out even worst, is that normal(to use MS-Paint anyways?)
Again thanks, I'll give it another shot myself!
(Though the offer still stands for anyone looking to get in on this rom hack ;P)
