The creator of the game is very talented.
To express this, you would sign 'game', then 'creator' (combining 'make' and the 'person' marker), followed by 'talented'. In ASL, establishing the subject—in this case, the game's creator—before describing their traits is a very common and natural sentence structure for beginners to practice.

She is a popular content creator online.
You can sign this by pointing to 'her', signing 'internet', 'content', 'creator', and finally 'popular'. This sequence sets up the context of the internet first, followed by what she does, ending with the sign for the person performing the action and the adjective describing her success.

We thanked the creator for their hard work.
Start by signing 'we', then 'thank', directing the motion slightly forward. Next, sign 'creator', and finish with the sign for 'hard work'. Remember to use warm, sincere facial expressions that convey genuine appreciation when signing 'thank' to fully match the emotional meaning of the English sentence.
