Proposition – Powerpoint Template is classified as a minimalist presentation deck, when in reality it is absolutely filled with extraneous items, flares, drop shadows, and wonky geometric effects.
Strip all these things out and maybe you will have a minimalist deck, but it would be a better idea to chose another deck at the outset.
On the positives, the flat matt colour works well with the bold highlight tone. The desaturated photo effect also enhances the coloured elements of the photography.
Being generous, you could work with the coloured signature effect found on an introduction slide.
However, these aspects should probably just make it to your inspiration file rather than back engineering this over designed template deck.
The chopped elements feel like broken glass and consume much of the slide space, rendering the actual content to second place.
Besides the colour / desaturated photography alongside the bright tone, there is little to reccommend this template above a myriad of others available and ready-to-go.
