Ok, could you just do any fakemon of your own design? I am curious to see your skills because the two that you provided in your main post were not the most detailed. :/
It's not super clear what it is you're offering to do, which might be a good thing to make clear in your OP, as PokéMew did point out. I would also advise to make a couple of pieces that really challenge you, and post the results, so people can see what kind of approach you take. Detail is good, but don't over complicate it ^^
