YouTube thumbnail for oldschool RuneScape

Hello, I'm looking for a skilled freelancer to create a thumbnail for one of my YouTube videos about oldschool RuneScape. My main focus is on the gameplay, so the video will include content related to that. I have a specific character or scene I want featured in the thumbnail, so it is important that I get a freelancer who can make an image featuring this. Finally, I prefer a cartoonish style for the thumbnail so I am looking for someone with the ability to create a cartoon-style image. Thanks in advance for your help!
