Hi Doyaldinho,
Welcome, some good feedback available, as Naomi would have said if I hadn't (finally) beaten her to it is to join one of the groups. Culture here encourages reciprocal critting, so don't be shy about reading others' writing and offering your two cents either!
Cheers, enjoy etc,
Gaius
<Added>ps: Somewhere in that first sentence, please insert "best bet". EG: I am encouraging you to join one of the groups rather than merely stringing random words together for visual effect.
<Added>pps: Nngh. Ps is non-sensical also. Think I should give up this writing business, I am clearly illiterate.
