They are both impressive, but with the Ichigo, there isn't really any shading in the piece, which (funnily enough) makes it look flat, especially with the face. You kind of have shadows with the wrinkles (creases?) in his skin near the eyes, but they're not very dark, so it's easy to not notice them.
Maybe try on a new picture making the dark values very dark, because you can always lighten them with the midtones and the highlights. This will give your picture more depth and a chance to experiment with the contrast.
Do you have any original drawings, rather than fanart, that we can check out?
