Hello! This looks lovely... I am going to try and do a submission for this project soon as well. Have you ever tried to use Adobe Illustrator? When working with shapes for logos and graphics it is the superior program to Photoshop. You are able to work in vectors instead of rasterized pixels. Vector shapes are scalable where raster files are not, they are just set pixels and when you scale them they lose quality. Hope this helps on your further graphic explorations.
