add an additional floor or table lamp for improved lighting in the space revisit small furniture pieces and swap them for more functional ones if needed
add additional seating using ottomans or poufs — it doesn't take up much space or budget balance decor by adding texture for interest instead of bold color — wood, pottery, and brass are great picks
add plants — real of faux — to incorporate natural elements into the space and liven it up create cohesiveness with small touches like coasters + tissue box covers that repeat the same colors + textures in the space
