What do you currently like about the room and what don't you like?

Without any major changes, the aspects which jump out to me include the following: placing some tall, potted plants outside to provide a nicer view from the window than the fence; replacing or adding to the current window furnishings to add opulence (i.e. thick, long, dark curtains in a colour complimentary to the feature wall) and perhaps also sheer curtains to obscure the view of the fence; a painting or potentially an ornate mirror on the feature wall (i.e. something that will compliment the feature lighting); potentially a large rug under the table if you wanted to soften the room and to add an extra degree of opulence to make it a really "formal" dining room; the addition of a decorative element to the centre of the table or potentially a table runner in a complimentary colour to the chairs; re-arrange the objects on the side table to form a more traditional vignette on one end of the table (i.e. a grouping of three similar objects, but with varying heights); potentially move the high chair, although that's probably not a very practical solution if it's used multiple times every day.
