It's terrific to see you dress formally and well prepared for the speech， and your poster is well done as well.
however， you need to make more eye contact with the audience and better speak with various tones and clear pronunciation.
I have to say you are a bit stiff without proper body language， which is no good for impressing the audience and the jury.
Moreover， I really hope you can put more passion into the speech and try to enrich it with more facial expression， then surely your speech would be fabulous.
