Criticism is good lol... Anyways, its a good sig and the render fits it. Only thing that is a little bit off imo, is the text, but it still is a good sig. Gj
It's very over saturated, and needs more colour. At the moment, it's rather too monotonous. Also, work on text placement and blending a bit. It also needs a more defined light source.
Yes, but a light source needs to reflect on the render. there's no lighting effects on the render. Use a simpler font. Make it stretch out more. Use character spacing for that. Also, remove the stroke around it.
I think the light source should be in the upper right because you can see the head of the wolf is lighter than the rest of the body so it would make sense to have a light shining from the upper right, imo
