Welcome to the community @Kamala_Prasai!
I took a peek at your current portfolio and based on the layout I’d imagine you shouldn’t have too much trouble recreating it within Webflow. Since you mention not being able to make it exactly the way you wanted I’m not sure what would change on your “ideal” portfolio design, but there are lots of great tutorials available in the Webflow University. Taking some time to walk through that content will definitely make you more comfortable with the tools and everything is 100% free.
That said, where exactly are you running into issues with your current Webflow build? Giving the community examples (as well as a read-only share link to your project) can help in getting you good actionable steps to solving any problems you may be running into.
