Describe yourself: what colour are your eyes? Is your hair straight or curly? Are you blond or dark-haired?, etc.
nice to meet you
I am not tall; I have dark-coloured eyes and brown straight short hair.
In English, you cannot connect two main clauses (a main clause is a clause that could be a sentence) with a comma. You must use a semi-colon as I have done above, or a conjunction like "and", or make them separate sentences.
Thanks for the clear explanation.
