Hi Sheri! I think it is so important to remember that everyone is at a different point in their journey. Some have been doing this for a very long time and have worked hours and hours in Storyline. When learning something new, everyone looks back on their early work and cringes a little. Others typically see really nice aspects of your work, even when you focus on everything that is not perfect. Your picnic table setting last week was adorable and you successfully incorporated the illustrated character and background with the photo-realistic utensils, plates, etc.
As for resources for these projects, I've used freesound for music and sound effects before and freepik and Canva have some nice graphics. I also like to look at the layouts on these sites and see what I like and what works, then take that idea and make it my own.
Again, keep going. Keep learning and developing and your hard work will show in your e-learning projects!
