Well ... while I see that it may be great fun to test out HDR techniques and look at the results, I also find that not everything renders itself easily to HDR photography. This indoors motif does not. HDR technique is totally unnecessary, I feel. You can produce a pleasing pic with the given light dynamics in one photo, too.
And a photo with such a narrow DOF as you had here (to compensate the low light situation with a wide open aperture) gives itself even less to HDR. The first thing I see is that the WALL and the lamp post are in focus, but none of your intended subjects are: neither the sweets nor the koala. And the HDR gave the koala a dark "halo" (halos are bright in and by themselves, but what would I call that dark rim otherwise?) around his ear.
