Curious about the name, HDR -is that in reference to "hdr photography"?
Lighting looks like a well placed flash illuminated the owl in challenging lighting (based on how dark the background is). Indeed you've really captured the colours and richness of colour very well (perhaps a touch "over" rich compared to reality but not horribly so).
I'd have cropped the top and right side though; they are empty areas which really aren't giving much toward the photo, whilst all our attention is on the owl which is heading and looking into the lower left corner. So I'd crop the waste space away.
