I am sorry for the delay in answering your post.
Unfortunately, when applying for a spouse visa there are mandatory requirements, these are that you must evidence that the relationship is genuine, you must meet the financial requirements set out in the Immigration rules and you must pass an English exam to at least level A1.
Evidence to support the application on the above points is mandatory and as such you have't provided a large portion of the mandatory documents that the Home Office require.
You wouldn't have any grounds to appeal the decision because of the pack of documentation provided and I would advise that you make a new application, making sure to provide all mandatory documentation.
In regards to the Human rights section of your letter, after a refusal, the Home Office also consider any human rights grounds that may be a factor in the application.
You are free to make a new application and provide the required documentation.
