How do I change the scale of models?

Just in case, I'm not saying this for no reason! Everything is analyzed through comparison! Many people have succeeded! So you can too! There's nothing complicated about it! I swear!

Okay, thank you. I hope it works out. All that's left is to choose the right creatures from your website for comparison. Am I right in understanding that, for example, Dendroids have non-original geometry, while Pikemen have original geometry? And also, please tell me, can this effect be used to reduce the size of objects, or only to increase them?
