Well,its really cool! To sum it all up… but if i have to give critics… well, Dont use lots of images in a webpage… Give space to other elements and as others told me! Way more professional! Let the webpage breathe… atleast give it a blank space… Its up to you actually… but to be honest, detailed background overlapped with featured images is a bad idea for me! but anyways, great JOB…
Sorry for saying things like a pro… im actually a beginner as well… and because im a beginner, ill leave my portfolio as well and let you also give critics!
No bootstrap, i hate the way you need to be online in creating page with it… Its all full HTML CSS and flexbox!
