Probably no NSFW, but suggestive is fine.

About copyright: I retain copyright over created commissions, but personal and non-commercial use is allowed. An indefinite license for predetermined types of commercial use can be granted for an extra charge. However, you are granted a free license to use the image for livestreaming and video thumbnails/content, monetized or otherwise.
Basically in real people talk, all this just means is that you can’t sell a shirt with the commission or it or something, but you can like, still make a twitch emote or youtube thumbnail out of it.
