Hey Chexie, welcome to RMS Forums! Ugh, I find amazing the fact I've seen A LOT of people using those chibis all around RO PServers, Your work is hotlinked and spreaded around the internet, most people use them and don't even know there was a disclaimer about that, I've seen the HWizard one >9000 times, and nobody of them knew the source or the artist, since there is nothing on them to tell it, put a watermark on all of them like people do normally at DeviantART if you want people to ask for you permission, then send the one that isn't watermarked. If you want to take a more aggressive action, copyright them, I think that there are some sites who can do it for free, or I think there are.
Your links are broke, it's displaying 2 HTTPs, your Alchemist / Amistir art isn't hotlinking, some things I noticed.
Nice Colouring skills, but I think the hands on the on featured image is a bit too small in comparison with the rest of the body, but since I never studied Anatomy or anything like that, it might just be my eyes.
Sorry if something is incoherent, I'm sleepy.
