Regarding Adlar: He looks really great, except the right side (your/my right) of the cane seems to go behind Adlar and it looks a little weird. I think it should look like it's in front of him (like it is in the GB sprite). It almost looks like the side of the staff is cut off. Or is it just me? Well, it should be a very simple fix.
Regarding Nayru: Could you make her lower dress part a lighter blue (maybe take out some of the darker shading; have less contrast, keeping it lighter)? It seems like the lower part and upper part run together a bit too much. Also, her hair should be the most-blue part of her, and her lower dress part is a little too close to the color of her hair. However, I do not know how many colors you are using, so this may be an impossible request.
eyes should be feminine and btw: neither of them have mouths
The GB sprites don't have mouths sometimes because of the style and size of the sprites. But I think you have enough room to add a mouth and accentuate the eyes a bit more. She looks great, but the critic in me would give her 4 stars right now. A happy-like mouth would probably make all the difference to get a solid 5 from me.
All these FSA-style Oracle sprites are looking really great! I agree with Faldomar that the newer ones are looking better than your first ones. Btw, you should upload more of them into the resources so I can rate them.
Of course, I'm looking forward to more.
