Lighting is good except it need a bit of Hard white (very light tan/mostly white) around the front-facing edges with a soft underglow fading to fit the shape of its head because its a bit too flat of an orange up there atm. Over all blending and CC matching pretty good, notice how techniques from you signature come into play in other blending types. You can also try making a top layer (ctrl+shift+E) makes a copy of all visible layers, then use the dodge tool to try giving it that proper light shine. The greenery could use a little refinement to get the white edges here and there out try refine edge in the selection and adjust the edge to softly grab the white.
