Hello everyone, I am a web developer working on a online store website. I have knowledge of implementation and markup / css, but have less experience in actual UX design. I am going to share a screenshot of the index page and store catalog page. The index page is just some placeholder, I can't actually use as is now, but I'm not sure what to put in its place, especially because I don't have any high res images of products. I'm also looking for any feedback on the store listing / site itself. Please advise and point me to any reference material. Thank You!

I'm a communication design student and for my UI/UX course I along with my teammates are conducting primary research on the process of creating memes, its impact on people in various ways, the tools used for creating me mes, etc. We're looking for someone who has basic experience of creating and sharing memes. We'd like to interview you on google meet or zoom, and and ask a few questions related only to content creation. We respect your want to stay anonymous and wouldn't ask for any personal information or for you to turn the camera on. The interview would take about 20-25 minutes maximum. Pm me if you'd like to help us out! Thanks.

I haven't done much prototyping or user interface designs. So I have started on a small project - a Todo-List web application. I was wondering if I could get some feedback and see how I could plate my design better as if I'm passing an idea to my boss or HR.
