I think it would help if you could be more specific. Are you just looking for some fan-art of creatures of an existing game? Are you making your own game which you need artwork for? Do you plan to make money off of it in the future?
For instance, if you are working on a trading card project you wish to monetize, asking someone to do the art for free isn't exactly fair. If it's a legit job, it requires legit pay.
While if it's just a hobby project and you need someone to collaborate with, that changes things a bit. But that is something that's good to be open about.
Plus, it also helps if people here know exactly what you need. How many drawings? What size? Are we talking ballpoint pens here, fineliners, a dip pen? What kind of creatures? Reference material?
The amount of drawings at this time may total to maybe about 30, including a back for a trading card, health and special cards, and of course creatures.Sorry if I got your hopes up, but this isn't a job I could take up on right now; I'm in the middle of my exam project. The main reason I asked you to specify was so that it's a lot more clear for people who are interested. The amount of different drawings, for example, can make a huge impact on wether or not someone might have the time to help you out, you know?
When you need something commissioned, it's best to have as many important details at the ready as you can, even if it's simply a hobby project.
If no one here can help you, I'd suggest trying a place like DeviantArt as well.
