I REALLY do not mean any offense (no sarcasm), but your singing sounds drunk.
Your guitar playing - not really a problem.
Your singing - off pitch.

Sing along with easy songs (like Blowin' In The Wind) and make sure your pitch is the same pitch with the original song.
There is no 'Oh, it sounds similar' in singing - pitch MUST be accurate.
And again, just constructive criticism - no offense.
