Villanelle help please?

Iambic pertains to a pair of stressed and unstressed syllable. Penta stands for 5 like pentagon, 5 sides. Therefore Iambic Pentameter is 5 pairs in a line - or a line that has 5 pairs of unstressed and stressed syllable. That would be 10 syllables in all per line. Yours is 8, so it does not fall under iambic pentameter.
