This is a good candidate for a re-draw. Overall mantle/back, wing and head colors are too dark. Edging of primaries and rectrices should get attention as their typically olive/yellow/white showing. Wing bars can be black with white tips.
Position/shape of head and neck appears untypical and/or uncharacteristic --> treatment of the nape could use a bit more love both in shape and color.
Something isn't right about the face; I think it's caused by eye size and placement in relation to the flow of the bill. Bill shading doesn't reflect a characteristic look of the white-eyed vireo-- often you see a lighter gray toward the tip where the mandibles meet.
Leg color is a viable/useful fieldmark; they should show blue-gray.
Thanks for reading.
