You have positively awesome creature concepts, and the execution is perfect. They look somewhat frightening, but at the same time some have got this edge to them that makes them look like they could have more than just the typical scary monster personality. (Thorns and Arachne, for example.)
Don't be too modest, now. Even when you do monster "fanart", you interpret them so heavily and so creatively that they could EASILY pass for your own totally original creations. You have a knack for translating anything at all into your own special style.
Updated my sub-text and the banner (adding "and Artist" written in the 20 Cents Marker font in blue) to emphasise that I'm not just a media fan, but also an artist, since I developed many profile banners. My next goal is to create banners for three moderators.
