HDR and interiors are just made for each other, like Liz Taylor and Richard Burton or bacon and eggs.
I think that most people when they start off with HDR adopt a fairly heavy hand on the tone-mapping controls and end up with something way OTT for many people's taste. With time they usually become more restrained and go for a more natural looking result.
So this for me is over-processed but that said I like the saturated colours, the viewpoint and the bags of detail. I'd suggest maybe correcting the verticals using the image editing program of your choice as the uprights are all over the place at the minute.
Stick with HDR and enjoy yourself .... it's a wonderful technique.
