Yeah... What I'd do to that is I would sharpen and lengthen the spikes, perhaps define their borders a little better. Now the first impression is (at least to me) a long wet fur or flames.
Also other thing is shading. I can't quite easily get ahold of the overall shape as it is. For a first glance, it looks like like a big heap of fur or flames, only after some time I noticed all the arms.

One possibility would be to colour the background darker so that the shrike would kinda shine out of it.
It does look cool as it is, though. Only anatomical (lol, as if I knew anything about the vreature's anatomy

) anomaly is that I can't tell which one of its right hands is the upper one. The one it holds in fromt of it seems to start higher on the shoulder than the one it helds higher, but on that occasion the lower hand has very long upper arm, at least significantly longer than on the left side.
