Hi GarooStudio!
My name is Sarah, and i'm new to freelancer.com, but i hope you find after looking at my profile and my art that it's appropriate for the work you want. I've been drawing anime styled art for many years and i'm very confident with chibi characters (including having the correct proportions etc). If you need any more examples, let me know (i'm working on one at the moment that i hope to add to my portfolio by the end of today).
Also if you find i have a somewhat different style than your reference images-i can easily cater the designs to look more like that style you were after.
Please don't hesitate to let me know if you have any other questions etc. I'd really enjoy doing this job for you!
