OP Really, really well done for bearing up in the face of a lot of criticism, including from me. It can't be easy.
A previous poster said your house could never look like The Red House pic that I posted a link to. We no, of course not. That wasn't my point. Why I posted that link was because it showed several elements of typical Arts and Crafts styles. (Texture, surface decoration, patterns from nature, honest natural materials, fine, individual craftsmanship and sometimes wobbly hand-made irregularities; things not matching; integrity of the materials worked with - everything looking like what it is; natural, earthy, even sludgy colours; a fondness for leaves and branches and twining vines and birds and bees and flowers ... warmth, homeliness, natural-palette harmony)
Some of these features are still there in your house, eg the (fabulous) windows and the front door. But for the rest, at least in my opinion, what really unsettles the viewer is that the decor is too full of high contrasts (black/dark brown vs white/pale neutrals in living rooms (that's Art Deco and something very different and not at all welcoming or restful) ; deep venous-blood red and white - like an operating theatre! - in the kitchen. The floor may be oak but in the photos it looks like cheap laminate; why not a darker shade? why so high-gloss? why not wider natural-looking floorboards or even parquet (as it would have been)? The hard-edged leather sofas are mid-20th century industrial-modern. The black-slab coffee table looks plastic (I'm sure it's not - that's the fault of the estate agent's photos) and modern and industrial, which is the absolute opposite of arts and crafts style. The kitchen is industrial, too: gloss-white, sharp-edged..
As I said before, this is just my view. I am almost certainly not representative of your potential buyers. But - like other posters - I was hooked by the words 'arts and crafts'. Can I (respectfully) suggest that you re-market the house using different key-words such as 'spacious' and 'recently modernised' etc etc? And above all stressing its location, which is, for a certain market, clearly very, very desirable.
Best of luck.
